High School: Watercolor
Here's a photograph of a watercolor painting I did as part of one of my high school art classes.
I was experimenting with the technique of laying down some rubber cement before you paint, and then when all the paint is dry, you brush off all the rubber cement. This technique is a lot like batiking I think, although I haven't yet tried batiking.
I was also experimenting with these new watercolors that I had just gotten. These weren't the usual cake watercolors, or even the tube kind, these were liquid, and could even be used as ink. The brand is Dr. Ph. Martin's Hydrus, I think one or two bottles out of 12 or so have actually survived.
