At my Saturday workshop we painted on YUPO. Been a while since I painted on this surface but we all picked it up rather quickly. Being a subtraction surface it's really fun to paint snow scenes. Cut out stencils for the trees, rolled gouache, and then painted the rest with a dagger brush. This one is quarter sheet for a demo and maybe half sheet would work even better. For me I like how you become more of a designer using Yupo and stencils. Give it a try. If you don't like it just wash it off.
