Dr. Ph Martins watercolors. Such rich pigmented colors, a little goes a long way. This is a sketchbook I am using, not watercolor paper, so it doesn't work really well when it's all wet. But, I love those colors, they're a little pricey but worth it if you can swing it. I cut out some images I wanted to play with and then just doodled on the whole thing while watching TV, is there anything better than that, doodling and being brain dead watching (or I should say "listening" to) TV. Very soothing! LOL!
