Okay -- today's challenge was more pressing than usual. We needed to bring in something edible to paint. I decided that a nice sandwich would fit the requirements by being colorful and having different textures. But there was one catch, the sandwich was my lunch and I couldn't eat it until I finished the painting. This is called "motivation." You can't take all day on a painting if you're waiting to eat it! Anyway -- with apologies to poor Susan who was sitting next to me and getting a whiff of the onions for a couple of hours while I sketched and then painted -- it was an interesting assignment.
