Leave it to British accessories designer Hindmarch—known for handbags with a sense of humor—to put a lighthearted spin on a weighty issue. Hindmarch is doing her part to encourage eco-friendly living, with a reusable shopping bag that sassily declares i'm not a plastic bag. Unlike most drab canvas totes, this bag is one that people are bound to want to carry more than groceries in. The British version, above, is available on Hindmarch's website and, come July, will get more exposure when Whole Foods Market begins selling an adaptation for the U.S. in some stores.
