I have never made napkin rings, but polymer is plenty strong enough without using the keyring as a core. People make jewelry-rings & bracelets that are strong enough without one. Unless you have some “wild napkins” (lol) or the if rings will be getting some really rough handling. As far as thickness, they should be made *at least* as thick as the thickest setting on a pasta machine (1/8″ or 3.2 mm,) or even double that. It all depends on how you plan to decorate them. (Will you be adding more clay like with cane slices, or sculptural elements?)

If you decide to use a keyring core, you would have to wrap your clay around a mandrel of some sort, sized just under that of the keyring. There are a couple ways to do this — or maybe you already have this figured out? Let me know if you have more questions, and I can give you some ideas about how I think this could be done. Also, do some looking around the blog. There is alot of information here. I’m still trying to catch up on it all of it myself!

Happy claying!
