We received a metal cross from World Market for Christmas. It was just begging me to alter it today - so I glued hundreds of polymer clay heads on it. I made the heads a while ago intending to use them in an art project that just never came together. I have a nice blister on my palm where a glob of hot glue landed by mistake.
Had I been paying attention I could have told you how many heads were used. I know I went through at least 8 hot glue sticks. I already have it hanging on the wall. This was a fun, quick project if you have hundreds of polymer clay heads already made and baked.
