Cabochons

Cabochons are at domed flat back shapes that can be either set into claw settings and usually fixed with glue or a more popular method is to bead a bezel around the shape. 
For gluing to metal we would recomend using a small amount of two part expoxy glue glue like Devcon and for gluing to fabric a fabric glue like Trim It. See our range of glues here.
