Rob and I have been working with polymer clay as of recent. We've only been making polymer pieces for about 3 weeks. He is focusing on making bears, while I have been working on the food side - polymer cakes, donuts, cupcakes, pies, etc... I'm truly addicted to making "food jewelry". I think they are unique, and they are a treat you don't have to regret on the scale.
When firsting starting with polymer clay we had also purchased the recommended sealer. This stuff was aweful. It destroyed our brushes, and left the beads sticky. That simply did not work. So, we tried a more uncommon avenue... nail polish top coat. This works like a dream! We have also used top coat with glitter in it already, and that gives the beads a nice glimmer.
Attached is a photo of a pair of chocolate cake slice earrings I recently finished. I'm very attracted to "food related" jewelry - must be because I'm a Food Network addict.
