9"x12" watercolour on arches watercolour paper. The paper that I worked on was really interesting, it was very heavy and absorbed the paint almost immeadiatly, and made for a very different painting experience. I just bought a small pad of it at the store, and I don't see on the package what makes it so different, but it is, and I liked it :) ps I know it says ebay sample, and I know it's not an ebay sample, but unfortunatly it's the only properly sized image I still have of this one :)
