Sometimes I think that 60% of a painting is done in the very first wash. Here you set the base colour for your picture, establish the major forms and (if you remember) reserve a few bits of white paper for highlights.
After you have worked the first wash over the paper and dropped in any stronger colours, you have to let it dry completely. (In the picture below , this was just as well, as I was late for work…)
