In Jos Smith's book The Pen and Ink Book, he (she?) says "For years Picasso deleted accidental passages that 'worked,' then attempted to recapture the effect intentionally. His reasoning was that something belonged in a picture only if he could include it at will. What could not be repeated had no place in his work. This approach, in which you become a student of your own drawings, is one way of assuring growth in your work."
This is exactly my goal (or one of them anyway)--to be able to DELIBERATELY create something. Most of my pieces that I like the best are accidents. The things I've been posting in the past several weeks are not.
