I’ve always admired the artists of long ago who mixed their own pigments to make paint for their artwork. Maybe that is why I am so fascinated by making my own pulp paint:
I start with cotton or flax fiber that has been processed in the beater at least six hours, making a pulp that is fine enough to spray through a household spray bottle.
The pulp is strained and then pigmented by hand to create a palette of colors for painting. I then add water or sometimes methyl cellulose to achieve a medium close to a gouache watercolor so that I can apply it by hand with a brush, squirt it through a syringe or spray through a bottle onto freshly-made sheets of Asian-style handmade paper (i.e., while the sheets are still wet and before they are pressed).
The pressure of working while the paper is damp/wet forces a spontaneity that is exciting and challenging as it requires my full attention; once I start applying the wet pulp onto wet paper, there is “no going back." (there is no erasing in the process)
Why go to all of this trouble?
It allows the painting to physically become part of the paper substrate, creating a mysterious surface and effect that can’t be achieved any other way.
