Last year I bought a bunch of brown card style paper from Guerilla Painters, put it in the backpack that I use for outdoor painting and then forgot to use it. I finally remembered to add some masking tape to the pack so I could tape the paper to a panel - I decided to use it today. The paper takes a little getting used to because it is somewhat absorbent but I adjusted pretty quickly and enjoyed the experience. You can't really see just what I was looking at in this photo but for some reason I thought having some background might be neat. Plus, a wet painting on paper is pretty hard to put anywhere to take a photo!
