These are some simple tube set rings that I have been playing with. I am trying to develop an easy project that students could do in a one day class. While I like these, the project is not quite easy enough. The tube is a bit wider than the ring shank and I have to carefully fit each tube to the shape of the "Crazy 8" wire. The result is pretty cool looking but not easy enough for beginning students. I have some more ideas to try and will post pictures of them when they are done.
