Another fun thing I have been doing is making "blob animals". I have two of Carla Sonheim's books: Drawing & Painting Imaginary Animals and Drawing Lab Mixed Media Artists Exercises which are both a lot of fun. One of the exercises is to make a watercolor blob and see what kind of imaginary animal develops and take it from there. It's a great deal of fun for anyone, but as an artist, it provides that child-like freedom of drawing/painting without the obsessive judgment that we frequently inflict upon ourselves.
