So yeah. These have like two more coats of paint on them now since I took this picture. But they're so awesome-looking and I can't wait until I can put them on the line between my swords. Solid craft foam and hot glue! They each weigh like as much as two large turkey feathers, so maybe like a half ounce each? It's so awesome. They won't weigh down the center of the connecting line at all. The main shape is made of 6mm craft foam, and then the raised edges are 2mm craft foam.
