In the experimental drawing workshops, we worked on two pieces in parallel. The first started as straight non-overlapping lines in charcoal and was posted as “Wildcode“. The second was built from curved lines, always reserving an area of paper free of carbon stains. This was then stored on a rack. When I looked at it a week later, it had acquired an imprint of a piece of metal that was more interesting than the original drawing. I built on that in charcoal layers, then throwing white gouache at it. This is fixed and photographed. I have cropped and tinted the image using Artrage on the iPad.
