My brush painting 6 classes later! It's fun, but I don't think I will continue it (at least not now). Brush painting is more about spontaneous expression--one just starts a new painting over and over again until it satisfies. For me, used to being able to sketch, erase, paint over and fix, it can be frustrating. I don't like to cut my losses and start over, I like to doggedly work on something until I get it right.
But I am glad I did it, I remember what I needed to know to write "Dumpling Days" and maybe I'll go back to it someday!
