Early exercises in Painting the Impressionist Watercolor encourage simple two paint wet in wet paint play. Set the range of values with only these two paints. I rather enjoyed playing with these cadmiums--Scarlet PR108 and Yellow Pale PY35.
I've been going through one of my phases of dissatisfaction--progress is too slow, things just don't look good, etc... So rather than wallow in my madness, I finally kicked off my plan to turn the spare room (a mess in its own right) into my studio. It's not yet a beauty but I now have a real tabletop for my paints. The kitchen table now belongs to kitchen activities! Seems the living room and the bedroom both also had their share of art toys, and now everything is in one place. Turns out I'm not the only one excited over this--Timothy the cat is flying about the house, howling when he stops to look wildly about.
