You're a girl after me own heart sure ya are! I love to repurpose. I'm so mean frugal I cut the tops off of plastic milk bottles and use them as plant pots.
I recently used some trays we got with deliveries plus a left over piece of plastic roofing to construct a covered dust bath for my chickens. I'm not at home or I'd send you a photo, so you're gonna have to trust me on that one.
