I love Kate Bingaman-Burt's work for some of the same reasons I like Martha Rich. It's simple and has a sense of humor, but is also meaningful. My favorite are her daily purchase drawings-simple pen and ink drawings of items that she's purchaced that day. I think it's unintentional, but she makes a statement about American consumerism. There's something about "tracing" your purchases that holds you accontable, and makes them more real.
Also check out the embroidery patterns from Sublime Stitching which she designed as a tie-in for the forthcoming documentary Handmade Nation.
