In celebration of Earth Day, I'd like to point you towards my friend's shop on Etsy. She makes reusable shopping bags out of recycled rain coats!
You get two bags (which fold up nice and small) for 10.00. They're machine washable, and it's one of the coolest examples of recycyle and reuse I've ever seen!
Her shop has a variety of cool things, so click here for her main shop.
Happy Earth Day!
