I have taught a Mathematics of Origami course at Elon University for more than 10 years. As an artist, I work with sheet material including paper, wire mesh, and sheet metals.
Rings of Revolution

Cardstock which is gold on one side and silver on the other.
In the history of vaudeville, there was an origami act called the troublewit. It used a single piece of paper with accordion and reverse pleats to tell a story. This piece was initially inspired by the troublewit.

This piece uses a single silhouette to show multiple solids of revolution. While I use large paper to show these concepts in the classroom, I had the idea to try this on a jewelry scale. I have created paper rings which can show solids of revolution. One is shown unfolded while the others look like a bottle or a glass as the silhouette is revolved about each vertical edge of the ring.

I can easily print these out and have students fold them to reinforce the concept in class. They think math jewelry is cool!
