I wanted the final product to be a little more resilient than polymer clay, so I decided to take a class in silicone mold making and resin casting,(actually this whole thing has been a bit of an excuse to learn more about that.)
I’ve never tried any kind of mold making before, I was surprised at how much detail it was able to pick up (glad I sanded the head really well.) The ears broke off when I removed the original from the mold, but oh well. I wasn’t planning to hold onto it anyway. Going to have to do a few more casts to try to fix the air bubbles in the ears.
