These lovely seahorses ($40 for the set) by Snaulkter are made from 99% recycled materials; old (washed) sweaters and plastic shopping bags in the fins to make them crinkle. Not only do I love these guys because they are upcycled, but they are totally kid friendly. I could see my kids spending hours making up stories about the Papa Seahorse and his babies. What an awesome use for an old sweater!
