Fish! They are fun to paint! I've done several sets of four, all the fish are different. They are cut out of heavy canvas, usually the ends left from making a floorcloth. Then I prime them and paint the fish, then varnish with several coats of acrylic varnish so that they are wipeable. They last for years, I know because I gave a set to a friend 4 or 5 years ago and she uses them constantly and they still look new! The backs are painted too, with waves in shades of aqua.
