I decided to use an exercise that I'd tried before. I set my watch for 30 minutes and took only 20 strokes to do each painting. I used a 6 x 8" canvas and picked photographs I thought would lend themselves to this idea. It really helps to mix up all your colors as best as you can before hand. Then use a big brush, because you need to scoop up lots of paint so you can do a big section with one stroke. As long as your brush doesn't leave the canvas it's still the same stroke. So the sky in the first one was done with one stroke. try it - it's really fun and the results are pretty cool.
