had to paint light through trees in watercolor. The pattern on the chair was a pain in the butt, but I think it came out ok. Winsor & Newton professional watercolors on Blick premier cold press 140lb watercolor block. This is the first time I've used Blick Watercolor paper. It held up well, but the painting came out kind of light (not sure if the paper had anything to do with that, though). At any rate, I bought a bunch of it, so I guess that's what I'm using!
