I used tin snips to cut out pieces from cookie tins. Then punched holes in both pieces and used rivets to put together. The "25's" were glued on with jewelry glue. So, it's really easy to assemble. If you don't have a rivet hole punch, just use an awl. push the rivet into the holes, and use a hammer to smash them down. Connie, take Paul's class. It was great fun!
