I taped as many of these small (8″x5.5″), crumpled sheets as I could on a plywood board I use for stretching underweight watercolor paper. I covered the board with eleven of them.
Then I used wide brushes to paint on this prepared surface.
I like the coherence of this study, as the design transcends the black grid borders. I hope each component can stand on its own as complete.
Note: Before I took the grid apart, I rubbed it with the side of a charcoal stick. This darkened the high points of the paper. Unfortunately I did not photograph this stage of development.
