I found some powdered milk and made some milk paint using liquid watercolors for color. Mixed thicker than a 1 to 1 ratio of pwd milk and water, it leaves a glossy finish, otherwise slightly more opaque stain effect. I still have to figure out how waterproof it is, whether it can be chewed on without staining or running. I also purchased some Claphams wood block and salad bowl finish, that is still in experimentation too. My arms hurt this weekend or I'd have cut out some more fun things... maybe tonight!
