I am sooo very inspired by this q & a with Kate Bingaman Burt over on My Love For You. Kate did the handlettering in Handmade Nation and writes the blog Obsessive Consumption. She DRAWS all of the things she buys, and draws all of her credit card statements.
You need to read the interview and check out her blog. It will change the way you think about shopping, consumption, and your general relationship with money. Oh and art and craft too:)
