I have my standard surfaces I love to paint on; Arches 300lb. cold press, Arches rough, Saunders Waterford. Whenever I'm at the art store I like to pick up different papers to experiment with. That's where Yupo comes in. Basically Yupo seems like a frosted piece of celluloid: it's plastic, non-porous, and weird. The paint tends to sit on top of the surface and dries really slowly. Granulation- that notion of pigment dropping into the crevices of the paper- doesn't exist. Instead the paint tends to swirl around with the slightest movement of the board.
Well, here's the result. It's a good test of letting go of control and allowing the paint to do its thing.
