A cabochon, or "cab", is a flat-backed piece that is void of any holes or channels. Cabochons can be used within many different mediums and techniques to create a beautiful finished piece. You can glue on a bail, bezel set, wire wrap, use them in a PMC creation, or even peyote stitch around the cab. Even further, cabochons can be used in mosaics and stained glass panels. The possibilities are only limited by your imagination and ability.
