Every time I recharge my brush (that is, dip it in ink) I test it with a few strokes on a scrap of paper before I risk it on my artwork. I decided to try and make drawings with those test strokes. It was a cool experience, like what I imagine the Japanese art of Sumi-i must feel like. I just look at the paper and intuitively make one or two strokes that feel like they'll add to the drawing. Then I go back to inking my comics untill the brush needs more ink and I do a few more intuitive strokes. The ensuing image tends to be a neat surprise. If I wasn't inking something else at the same time, I'd never have the patience to make this kind of drawing. I'd rush it and over work it and it wouldn't have the same simplicity and clarity.
