Sketchbook Project

So I just signed up for the Sketchbook Project, Volume 3, over at Art House. Art House aims to build art projects and communities. For this project, they send you a small sketchbook, which you fill and send back to them. They then take the sketchbooks on a 6 city gallery/museum tour. The theme is "Everyone We Know".
It costs $18 to participate, which isn't too bad. And if you send a self addressed stamped envelope, they'll send you back your sketchbook.
Check out some of their other projects here.
