Craftiness runs in my family apparently. My dad recently participated in a polar bear plunge and the theme of his team was"rainbow" (like pot of gold, leprechaun, cloud, the whole thing). My dad was the cloud, so this is what he and my mom came up with. It's pretty awesome. He didn't want it to be too fluffy because stuff like batting gets heavy and is hard to swim in. He created this out of tulle, some cardboard, tape, and 1/16 inch dowels bent into a circle.
