I started with a grid that I printed onto a white piece of watercolor paper. At first I chose colors to blend on purpose then I decided that the only way to ever remember what colors I was using was to number each color and write the number in each corner. As I was numbering the few that I had already done I decided to just randomly number each square without looking at the color the numbers represent thus making the blend colors completely random, blends I may never have tried on purpose.....better. After I finished I filled in all the background with a black, broad tip, sharpie.
I'm thinking there are inches in there somewhere just crying to come out.
