I work primarily with polymer clay, but I also do a bit of wire work, often with copper wire. I love copper and think it goes with everything. I sometimes make my own findings, especially for necklaces.
I love making bangle bracelets, and I put a lot of effort into sanding them to perfection. It's a lengthy process, but once you've touched a piece of well sanded and polished polymer clay, you'll understand why it's worth it. I usually describe by saying it feels like silk to the touch, but it really doesn't feel like anything else - polished polymer clay is really a unique tactile sensation.
