I haven't had much luck with finding patterns for Pendants. I'll make them once in a while when I have nice looking, exotic scraps of wood. Usually I just hand draw a shape onto the wood (i.e. a Heart or something along those lines) I use the scroll saw to make a basic shape, then I go to the belt sander and round the edges and finish with a bunch of hand sanding.
You can buy different clips plated in gold or silver at places that sell crafts. If you would like, Shoot me a private message with your email and I can send you a picture of a few I've done.
