In his blog on July 21, James Gurney gave a nice lesson on doing watercolor sketching, starting with a pencil sketch, and then what he calls a "ghost wash", a wet-into-wet watercolor wash, in order to establish colors and tones in a lovely, soft mush. Then as the paper dries, smaller brushes and more details can be added.
Usually I begin with lines; I thought I didn't like the wet-on-wet look. But now I wanted to try it. So I have been experimenting with it this past week, with results much more pleasing than I would have thought.
For this, I sketched Tofu sitting on the couch reading a book, but then he left before I could put any color on the page. But the next day, with the same kind of light, I sat in the same place to paint. Looking at the couch without Tofu there, I didn't have an exact reference for the shadows on his body, but I could see more or less where the dark and light places would be, and make educated guesses.
I like the contemplative mood that the softness gives to the picture.
