If you are lucky enough to have a set of metal circle cutters, they can be used for more than just cutting circles in clay.  The largest cutter can be set on your baking tray and used as a "corral" for your small round beads so that they don't roll all over the tray.

The smallest cutter can be used as a baking support when you want to bake a Premo! Sculpey Jewelry ring.  Just set the cutter on your baking tray and drop the ring portion into the cutter.  The clay will be supported on the top of the cutter when baking.
