Pollution, art and making pigments

I have been asked to work with first year studio 'P' students to look at some pretty basic questions concerning 'what' people paint with. One of the issues I have touched upon in this blog is sustainability, so as well as asking students to explore where and how different paints come from and who is involved in their manufacture, I am highlighting the fact that the process of investigating these things is as much about art making as anything else, and can lead to a much better awareness of the relative carbon footprint of different approaches to art making. This also helps to question the position of painting within the art canon and to open out a dialogue with other ways of making meaning. Painting perhaps being just one element in a practice that extends to engage with relational practices, video, photography and other art forms. 

John Sabraw using a glass muller  to grind his own paint

The artist John Sabraw makes his own pigments, including strong yellows and reds made from the oxidized 
sludge of abandoned coal mines in Ohio. I was interested in this because he is embracing pollution, seeing it as something to engage with and not just moan about. The paintings he makes with the paints could have been totally abstract as far as I'm concerned, it was the thinking process that led him to work with others to make new pigments, that I thought was the most interesting aspect of his practice.  



Pigments are everywhere. Natural pigments can be sorted into three categories: those obtained from plants, those from animals, and those from minerals. Every bit of ground is a collection of various chemical compounds and minerals, some already in powder type forms and others needing ground down. Sometimes you need to heat them to intensify the colour and before doing that you would also wash them, which strengthens and also intensifies the colour.  Some artists use natural found colours very directly. Every sand drawing is done in whatever colour the sand is.

Look at how the difference in colour intensity changes the way we read similar approaches to making images. Even at such a basic level, colour is operating powerfully, but is this painting? As this is a blog that centres on drawing I could easily argue that it is coloured drawing or drawing in colour, the reality is that it doesn't matter and this issue over whether something is a drawing or a painting is actually a problem with how words work. (Read the first paragraph of this old post)

herman de vries, (he never uses capitals when he uses his name) is a Dutch artist that travels the world collecting soil samples. The concept he works with is that all nature is art, therefore putting capital letters in front of our names signifies that we think we are more important than other things. I like the way that he follows through his ideas. 


From the earth: herman de vries

A typical herman de vries installation consists of an array of collected soil samples from various parts of the world, they are simply used as pigments and samples put down that are always the same size and which are then archived in special boxes and then brought out at different times for exhibition purposes. (This post on documentation describes the process in detail)

Yusuke Asai

Yusuke Asai also searches out earth pigments. He talks about making images with dirt and mud, making installations using coloured soil collected from the area local to the places he works in. His work is much more to do with the illustration of folk tales than a simple documentation of the soil colours he finds. 


Detail of the surface of one of Mark Bradford's paintings

Everything is though nature. We are of nature and the environments we make are also part of nature, we might like to think of nature as an idyllic other thing over there that we have not sullied or dirtied up with our pollution, but we are actually one of nature's animals just like all the others. Therefore Mark Bradford's collecting of street papers and other detritus and use of them to create paintings, is just as environmentally sound as herman de vries' work. There is a detailed post on Bradford's practice as part of this post's reflections on collage, however he says of himself, he is an artist that paints with paper. 

Whatever you use to make an image with will carry some sort of meaning, but we sometimes forget that this is the case. Compare these two images made using various pigments.

Vic Munoz ‘Valentina, The Fastest’ The Sugar Children’:1996

Vic Munoz made this portrait of Valentina using sugar, sugar a substance which for girls like Valentina is both a future and an existence. (Read about this in more detail here).

John Singer Sargent had a remarkable ability to draw with a brush. Because of this he was the painter of choice for many of the rich and famous of his time. Typical of his work is this portrait of 
Lady Agnew of Lochnaw.


John Singer Sargent: Lady Agnew of Lochnaw

Gertrude Vernon was born in 1865 and married Sir Andrew Agnew, 9th Baronet of Lochnaw Castle, in 1889. The public success of the painting apparently endowed her with additional notability and prestige. It still still hangs in its original antique French rococo frame. It is painted in oil on canvas and measures 50.0 × 39.8 in. At the time Sargent would have obtained his art supplies from companies that you might well still recognise the names of, such as Winsor & Newton and Reeves and some of their archives still survive. The beautiful soft tints whereby he was able to subtly modulate the appearance of light reflected off various surfaces were mixed using lead white. Several painters have historically been known to have succumbed to lead poisoning including Rembrandt and Goya, but the workers who made the paints in the 19th century were exposed to much heavier doses of its toxic fumes than an individual painter. A blue-purplish line along the gum, was a typical trait of the intoxication, and mental disorders often resulted from ingestion of even minute amounts of lead. Because its effects were often at their strongest when young children were exposed, in the UK, children were finally forbidden to work in white lead factories in 1878. Neither Sargent nor the Lady Agnew of Lochnaw, would have been worried about the conditions of the workers that made lead white. 

Human lives and the material substances that go to make up the world are always inextricably entwined.

Collage part five: Gordon Cheung

Gordon Cheung in his studio

We have looked at collage several times before as a way of drawing directly with the world itself. Collage materials are wonderful in that they bring into your work all the associations and stories linked to their previous life. 
Gordon Cheung uses collage in such a way that as well as bringing in those associations he uses collage as a bridge between drawing and painting.


Tulipmania

The image of the tulip above is typical of Chung's use of collage as a support for his painting. The background is made up of sections of the Financial Times stock exchange lists and its pink is a colour that has long been associated with the newspaper. In 1893, The Financial Times, began printing its articles on light salmon pink paper, which was meant to distinguish the paper from its rival the Financial and Mining News. Of course it was also cheaper to print on unbleached, slightly pink paper at the time. This decision would turn out to be the most significant branding step the company would ever take. The Financial Times is still pink to this day, and its colouring has become its distinguishing factor. Over the years, it has intensified its pink as the company’s brand has become increasingly synonymous with the colour. Chung has been using Financial Times listings for the support of his images for some time now and just as the pink of the newspaper became a recognisable brand, the use of the Financial Times in his backgrounds has now become a brand for Chung. 
His work reflects on the power of money to drive the art market and many of his images also comment on the role of investments in world affairs, therefore the fact that he has developed a brand or trademark look is a vital part of his conceptual remit. 
At one time the tulip was central to an economic boom in the Netherlands. 



This tulip above, known as "the Viceroy" comes from the 1637 Dutch catalog Verzameling van een Meenigte Tulipaanen. A bulb of this tulip would have cost between 3,000 and 4,200 florins, which was about ten times the average yearly wage of a skilled craftsman. Tulipmania, was what the boom and bust financial climate at the time is now called, thousands lost all their money by investing in this trade, a situation that has occurred several times in the history of the stock exchange. Chung by bringing together his painting of the tulip with the stock exchange lists, reminds us of the fragile nature of monetary value.


Top 10 Dead Celebrities Still Earning, No 8. Andy Warhol

Many of Chung's other subjects reflect the interrelationship of money, investment and art, his series of images, 'Top 10 Dead Celebrities Still Earning', a reflection on the fact that when famous artists die, their wealth often increases and value is as tied to the blue chip investment houses as to any form of cultural capital. 

On top of his collaged surfaces Cheung often uses spray paint together with oil paint, both these mediums again carrying with them meanings associated with their various histories. Spray paint was an industrial finish but is now much more associated with graffiti, the 'paint of the streets'. Spray paint is the low art medium, whilst oil paint is the high art medium being the medium of choice for all those aspiring painters that wish to enter the pantheon of art saints. Therefore when Chung uses spray paint to create a 'halo' around Warhol's head he is conjoining several different concepts. One being the central position of religious painting within Western art and its status of being an activity practiced by the first artists to become famous as art heroes, as in Vasari's 'Lives of the Artists'. In this case it could be argued that in Cheung's image, Warhol becomes an art saint. The other being an awareness of all those anonymous graffiti artists that work on street walls in every Western city; spray paint is their medium of choice and although 'tagging' is about having a street 'signature', for most people these street artists are nobodies. Before Vasari artists tended to be anonymous and in many other cultures artists never achieved the status of cultural superstars as they did within western culture and therefore also remained anonymous. Finally the bright streaks of oil paint and accompanying drips, reference the honorific value that oil paint has as a signifier of 'proper art'.  One of the reasons collectors are drawn to Cheung's work is that it still has the cachet of oil painting, which has traditionally been the most bankable or  ideal investment.
The key issue here is how the various associations with each medium combine to make a complex interrelated set of ways to approach Cheung's work. Collage materials will always carry with them a past history, but we often forget that so do all the other materials that we use to make art, such as those that seem 'normal' or 'the right' materials to use, especially those that you can traditionally buy on a visit to an art suppliers.

More thoughts about paper

Auerbach: The ability of a paper's surface to withstand erasure is as much a part of the final appearance as the quality of charcoal used, type of eraser and intent of the artist

In one of my posts on erasure I mentioned that I would return to thinking about papers for drawing again at some point. Artists will often have a preferred set of papers and paper boards that they use for different media and I think it is worthwhile looking at why certain paper surfaces are chosen by artists for particular jobs, even if only to then decide that that is precisely why you would not use them.
The three basic types of Watercolour papers

There are basic differences between printing, watercolour and drawing papers. I have mentioned Mohs hardness scale before and once again this is important when considering what a paper is for. A drawing paper needs to have a hardness that will ensure that the graphite or other dry drawing medium will pull off onto what in effect needs to be a harder surface. I.e. drawing paper for dry materials such as pencils, chalks, crayons etc. needs to have a hard abrasive surface. Watercolour paper needs to be tough enough to withstand constant wetting, so it needs long fibres, is usually of a much heavier weight to minimalise warping when wet and is unlike several printing papers not kaolin coated because it needs to maintain a certain amount of absorbency. Printing papers can be soft and thin, as they have to be compliant with the surfaces that are laying down the inks onto them and they tend to be much smoother, which is why they are sometimes kaolin coated. All papers come with their individual histories, sizes, specific technical specs and associations with other things, (I have mentioned some of these before), so there is no one paper that can be singled out as the best ‘art’ paper, but certain papers are used over and over again by artists, many of which have now become central to the business of art. The fact that many of these papers are of archival quality can be very important when it comes to customers looking at a long term investment. It is up to you as an artist to decide what will be the determining factor when investing in papers, price being perhaps for a student a very important issue.

Bristol board

A lot of illustrators and comic book artists like to use smooth Bristol board. The 500 series, 4-ply, 100% cotton, smooth Bristol (vellum surface) by Strathmore comes in 23" x 29" sheets and when I costed it today on Amazon it was £15.59 for one sheet.
Closely related to this is the Strathmore 500 Series Illustration Board, heavy weight white vellum finish is 20" x 30" and costs £13.99. There is no information as to why the proportions are different, I presume there must be some historical significance though. (Read this post on paper sizes)
Both these surfaces are sold as ideal for graphite pencil, coloured pencil, charcoal, sketching stick, pen & ink, marker, soft pastel, mixed media, oil pastel, light wash and collage.
However Bristol board has two working surfaces, front and back. This quality separates it from illustration board, which has only a front working surface.
The surface texture of Bristol Board can be either smooth, plate, semi-smooth or vellum. Smooth finish is also called hot press, and has a satiny, hard finish. Plate finish is very smooth, like glass and is excellent for maintaining the consistent and continuous line flow that you sometimes want when working in pen and ink; it is particularly good for using technical drawing pens. Vellum (or kid) finish is a medium texture more appropriate to friction-based media, such as crayon, chalks, or charcoal. Semi-smooth is an in-between surface that isn't as smooth as smooth, and not as rough as vellum and has come about because of the need for particular surfaces that suit specialty pens and markers.
An alternative finish, engravers or wedding, is manufactured for formal engraved wedding invitations.
Bristol and Illustration Boards provide stiff, strong surfaces to work on without the need for mounting. Bristol generally describes drawing paper that is pasted together to form multi-ply sheets. Illustration board has 100% cotton drawing paper mounted on both sides of a heavyweight board.
Plate Bristol board is great for scratching details out of ink drawing with a sharp blade, as it resists gouging and tearing, therefore you can be very sharp and exact with your removal process. Bristol and illustration boards will withstand a certain amount of dampness and so you can often get away with not having to stretch paper when using small controlled amounts of watercolour or ink washes, but on the whole they are for dry materials, marker pens or pen and ink.
Historically Bristol board has been used by illustrators and is therefore very good at sitting in the background when being photographed, something that in a world of social media is becoming more and more important. However its association with illustration means that many fine artists don’t use it, simply because they see it as being illustration specific. This is a very interesting point, one that has a history that goes back to a time when fine artists were concerned with Greenberg's ideas about media specificity and therefore wanted to distance themselves from illustrators. One of the biggest insults you could at one time give to an artist was to call them an illustrator. Things have hopefully now changed, I’m sure Andy Warhol as both an illustrator and fine artist would have known exactly how to use Bristol Board and would have used it whenever he needed to. As it was he used Bristol Paper to print on whenever he could. Some artists would never dream of using what are called 'fine art papers' because of their association with a particular type of thinking about art materials. There are a certain range of qualities that are expected of drawing papers and these often overlap with the papers produced specifically for watercolour or for working on with a range of dry and liquid art materials but, and this is the point that several artists would make, if you use non art papers when you try and make marks on them the very fact that these papers might be non receptive or designed for other uses, might make the marks you can make much more interesting. 
If you compare some more 'fine art' drawing papers to illustration boards, the ‘grain’  of the paper surface will often be much more visible, therefore it will become a vital part of the look of the final drawing. It is often expected that the fine art artist should have a 'rough' look to their work, as this has at times been associated with the idea of an artist's individual expression and a certain 'raw' look. This is the very reason why some artists don't use these papers because they are too 'hot', too close to the art business. Everything has some sort of meaning and artists that want to tap into less or alternate types of expressive languages may well use commercial papers because of their association with non art languages. For instance some artists only use office stationary to work with, because they want to make a statement about the relationship between what they do and the majority of contemporary work being done in offices. However the older I get the more I use 'art' papers because they have stood the test of time in relation to what they are made to do and I get get less worried about the associations they might have with the fine art tradition and I can afford to. (I have just ordered two sheets of khadi paper that have cost £36.30 each). At some point someone will ask you, "Why are you using that paper?", all I am suggesting is that you need to have thought about it. 

When working on Arches hot-pressed watercolour paper using graphite it has a very tough surface that can withstand a lot of erasure and is textured enough to hold enough graphite to ensure blacks are very dense, but smooth enough to ensure that tonal gradations can be very softly and smoothly gradated. A 9H pencil will still pull off against its hard surface, so you can use the full range of H and B hardnesses. 20 sheets of 18 x 24in will cost about £88.00 and you can get these papers in hot pressed, cold pressed or in rough finishes. Cold Pressed paper is often referred to as NOT paper meaning it is "not hot pressed". The surface of a Not (Cold Pressed) paper has a moderate texture or tooth in between rough and hot pressed. (See image near the top of this post)

Rough and cold pressed papers have bumps and grooves that hold onto water and pigment. They are therefore a good choice when working in watercolour and if you want to emphasise texture.

Hot pressed paper is much smoother. It doesn’t suck up the water as fast as the rough and cold pressed papers, this gives you more time to re-wet edges of pigment when working in watercolour, but doesn't allow you to get the same subtle gradation that a more absorbent surface allows for. Therefore if you are working in mixed media such as pencil and watercolour it will be the combination of how both graphite and watercolour works with the paper that will be important. 

Stonehenge hotpressed watercolour paper in comparison is smoother but softer. It will mark or gouge if you try and use very hard pencils, and it is harder to work up solid rich blacks when using graphite, as you need to create several layers to get maximum density. Its softer surface means that erasure begins to break up the paper and gives you a fractured surface, which is interesting but not always what you want. However when it comes to watercolour it is excellent with both wet-on-wet and wet-on-dry applications. It has a good absorbency that ensures colours stay bright and watercolour stays damp and sits on the surface long enough to keep blending and lifting colour off, so that you can eliminate rough edges between washes. Hotpress surfaces are often used by botanical illustrators, being smooth enough to hold detail but absorbent enough to get good colour intensity with smooth gradations. The cold pressed papers are often used by landscape artists, the constant blending and lifting it allows can lead to very complex subtle and atmospheric surfaces.

Strathmore 400 series pastel paper has an interesting ‘tooth’ designed to hold pastel but which can also be used when using graphite. Very dark blacks can be made by building up layers of soft graphite. However because of its very visible surface it can often mean that when photographed the grain is very apparent and does not disappear into the background. This may be useful to you or not, depending on how you want the image to work.  This paper has a traditional laid finish that enables you to control light/dark transitions using the paper surface itself. (These surfaces are 'ribbed' textures imparted into the papers by the manufacturing process of using a regular mesh lifted through a vat of floating dissolved paper)  Perhaps the best historical example of this is Seurat’s use of Michallet laid paper, whereby he uses the peaks of parallel ridges in the sheet of laid paper to both add texture and allow for highlights to softly emerge from the paper itself. The black Conté crayon he used builds gradations of tone embedded into the textured paper, and by drawing in this way he could minimalise dusting or smudging, which would have taken attention away from the control of form and into more atmospheric or emotional registers. (Look at the difference between working in a hard Conté crayon on a laid paper and soft charcoal, the crayon is hard and catches the edges of the ridges, but unlike the charcoal, doesn't break up so easily and therefore far less dust is produced, dust which will fall from the edges of each stroke made and will fill in the surrounding paper fibres)

Seurat

Cartridge paper is of course the paper usually associated with drawing using dry materials. I have posted on this before and will remind you that its ‘meaning’ is not just about whether or not it is hard enough or rough enough to draw upon. The making of Japanesepapers can at times be associated with an almost spiritual appreciation of both the processes of making and the various elements that go into the composition of each paper. 

It is time to remind you that from the most high tech industrial papermaking production methods to hand made papers put together on your kitchen table, paper not only serves many purposes it carries a wide range of ‘ur’-histories*. For some artists these histories will become more important than the media specificity of paper and you will need at some point to consider whether or not you need to take these types of issues on board. If you do, this can mean a lot of difficult background research. Research can though bring to light facts that can make for fascinating narratives. For instance the Montgolfier brothers who made the first balloon flights were paper manufacturers and they patented one of the first transparent papers. The Montgolfier family firm eventually became known through marriage as "Montgolfier et Canson", then "Canson-Montgolfier", then "Canson"; a name we still associate with fine art papers. "Canson" worked directly with Ingres to produce papers especially for him and many of the most famous artists of the 19th and 20th century used "Canson" papers. 
Capitalism is what drives so many of our ways of not only producing but thinking about business. The constant merging and buying up of companies means that it can be hard to keep track of what is going on behind the scenes of the products that we use. This is what has happened to Canson & Montgolfier over the past few years. The Arjomari company acquired Papeteries Canson & Montgolfier in 1976. In 1990, the Arjomari company merged with the Wiggins Teape Appleton group and became the Arjo Wiggins group. In 2006, the group Hamelin acquired Canson with all its subsidiaries. In 2016 Canson was acquired from Hamelin by the Milan based F.I.L.A. Group. The F.I.L.A. Group markets itself as being a leader in the provision of materials for creative expression. They now own brands such as Giotto, DAS, Daler-Rowney, Strathmore and Princeton, together with several others, supplying art materials and school supplies to world wide clients. The present Canson logo is a stylised hot air balloon that has been produced by a design team to symbolise both the history of the firm and its up-to-date Modernist credentials. 
The current Canson logo 

If you visit the current Canson company website you will find that heritage is very important to the brand and they run prestigious art competitions as well as showcasing a range of videos highlighting contemporary artists using their products. This is all very interesting because the status of the fine arts is in this case transferred to a company manufacturing fine art papers. This status will of course be partly used to justify the high prices of specialist papers. I am not trying to criticise this aspect of today's reality, simply referring to it in as a reminder of the bigger context. But as soon as this context is seen, further questions might be asked, such as, "How environmentally sensitive are Canson's manufacturing processes?". "What is it like to work for the company?" "How do they contribute to the F.I.L.A. Group's overall profit margins?"

Edward Allington often used papers from old ledgers to work on.  The specific nature of those ledgers providing a complex context that reflected his interests in the art of the past, the style of handwriting on old ledgers suggesting the importance of a trained hand for the production of legible script and the inescapable need for everything to be accounted for. 


Edward Allington
*Ur-history is a concept developed by Walter Benjamin, whereby all made things have 'material histories'.  Every paper will have a great number of people's stories locked into its production, some involved in forestation, some rag picking, some involved in manufacturing, some in distribution, some will be poorly paid, some will be high earning managers  etc. etc. each and every person involved will also be locked into an exchange of their time and labour for money. The stories of these people and how they have or have not reaped the various 'rewards' for their involvement in an object's production, ought not to be forgotten. 

At the moment I'm using some Indian papers, I like their unpredictability, they are 'hand made' and the amount of size in them varies a lot, even throughout a single sheet, so that as you drag a brush across a large surface you can get very different amounts of bleed. The paper is made from cotton sourced from scraps left over from the manufacture of T-shirts. I like the fact that this cotton was at one time destined to be something to wear. 

Obviously I could begin to list hundreds of different papers but that is really the job of a specialist, I'm sure you have got the idea by now that every paper needs to be treated differently, both as a physical object and as an object that has a particular background history. I think that all of these issues can be seen as stories, or narrative threads, and if you begin from this idea, 'once upon a time', you can develop a story by following what happens when you bring together a few different but associated threads. For instance...blue paper is a term that can refer to a variety of papers. First of all ‘blue touch paper’ is that paper we all remember from our childhood as being the soft paper that extruded from the bottom end of fireworks. It was used to make a slow burning paper fuse by being soaked in saltpetre and then dried. It was always very soft to the touch and I presume this was the result of 'scrunching' the paper, twisting it and untwisting it in order to break the fibres down and make the paper more like cloth. 

Blue touch paper

However in current journalistic writing, a blue paper is now something akin to a government ‘white’ paper, but it goes into high levels of technical detail. Historically blue paper as a drawing material has a different set of associations, first of all made and used in Venice in the 15th century and made from blue cotton and linen rags, it was often a colour of choice when making prepared paper, especially for silverpoint and other drawings that would also require fine white highlights. Blue was associated with spirituality and therefore its other-worldly colour was perfect for images of saints and other spiritual beings. Making blue the colour of the ground also serves to give the drawing a particular tonal register and associated emotional range.


Durer: fine brush drawings on prepared blue paper

By the beginning of the 19th century use of "variegated" blue papers (made from blue rags) was extensive. There was an expanded use of uniformly coloured light blue papers (made both by hand and by machine), especially for elegant writing paper as well as for sketching and watercolours. Artists and writers such as Turner, Edward Lear, Delacroix and Victor Hugo encouraging their use and maintaining an association of blue paper with the arts and elegance. Writing papers such as Basildon Bond have carried on this tradition; in 1932 Basildon Bond became the bestselling notepaper in the UK and the colour of choice when it came to signifying an upper class writing paper was pale blue. 

Jacqueline Kennedy: Personal letter about paintings for the White House. 

When you think of technical drawings you often think of them in ‘blueprint’ form. The blueprinting process was developed in the mid-1800s, when scientists discovered that ammonium iron citrate and potassium ferrocyanide created a photosensitive solution that could be used for reproducing documents. A drawing on transparent paper was placed over a piece of blueprinting paper, which was coated with a wet mix of ammonium iron citrate and potassium ferrocyanide and then dried. The paper sandwich was then exposed to a bright light, the two chemicals reacting to form an insoluble compound, blue ferric ferrocyanide (also known as Prussian Blue), except where the blueprinting paper was covered, and the light blocked, by the lines of the original drawing. The remaining soluble chemical is then washed away leaving white lines.

We now use the word 'blueprint' as an idea or plan for something, even though we no longer make 'blueprints'. The photography department in Vernon Street offers introductory sessions in making 'cyanotypes' and the chemical process is virtually identical to the blueprint process, so if you want to experiment with the process just ask a photographic technician. 


Paper stained with litmus is used to indicate the acidity or alkalinity of a substance. Blue litmus paper turns red under acid conditions, and red litmus paper turns blue under alkaline conditions, because of this sensitivity litmus paper technology is used in pregnancy test kits.

Blue backed paper is used for billboard posters to stop images underneath from showing through. 

It's interesting to now add to this blue paper research that idea we were looking at a couple of posts ago; of making images or developing ideas by bringing together a series of previously unrelated elements. In this case everything is linked to blue paper, but the differing uses and existing meanings are normally unconnected. What type of narrative could a slow burning paper fuse, something that is deeply religious or spiritual, the concept of colour signifying class, a pregnancy test, and the need to cover previously posted up images produce?  

You might find that the leap from looking at particular drawing papers and their specific qualities, to trying to stimulate ideas by bringing together different concepts associated with blue papers difficult.  But ideas that can be generated by bringing together different historical and conceptual associations are interesting even if only as a disjuncture. Finding connections between things can reveal unpredicted directions for your work to take and may eventually reveal an underlying network of previously invisible connections that lie behind things that we have previously taken for granted. One of the things you can do as an artist is to reveal to others what has always been there but which they have not yet seen. 

There are several other posts about paper (see below), read these as well, the clustering together of different strands of blog posts is designed to eventually make for 'chapters' or 'clusters' of ideas that are meant to work together.
