Baltimore-based artist Denise Tassin likes Necco wafers, a chalky sugar wafer snack made in Boston. Actually, I don't know if she likes to eat them (Necco is famous for being "the candy nobody likes") but she does like to draw on 'em:
They come in eight flavors and colors and make for an interesting art medium. In fact Tassin likes them so much, she has even been known to carry a pen and pack of Necco wafers with her wherever she goes. "It's like having a little studio in your pocket."
