So far, they've covered The Guernsey Literary and Potato Peel Pie Society, The Art Forger, The Language of Flowers, Z: A Novel of Zelda Fitzgerald, and this month, they're working with John Green's Paper Towns.
It's a really cool concept, not just connecting art to books, but CREATING art that's inspired by books. Anyway, it's a cool website & a good resource, and a lot of the basic ideas could be easily incorporated into book groups (or classrooms), regardless of age level.
(I mean, I think a lot of storytimes already incorporate themed crafts, as do book groups for younger readers. And way back when, I always did a craft with my high school book group, too, but somewhere along the way, I stopped. I'll have to Bring It Back when I get a high school book group up and running at my new library.)
