This is one of those ideas that will need to be "worked through" several times. I'm not happy with the first go around, but I'm learning from it.
I wanted a centerpiece for a sea food dinner; more of a tablescape. A mermaid vase full of flowers and interchangeable pieces around it and situated down the table runner on either side of the vase.
So I built the aluminum foil armatures. Made a huge mess with the CelluClay which is a ready made papier mache mix. Covered the armatures with the CelluClay. They turned out much larger than what I wanted. But, carry on I must; I've gone this far. Then I started covering one of the tea light holders with polymer clay and baked it. Turned out OK. I painted it, and moved on to the next piece. As I am working on all this, I realize I'm using a huge amount of polymer clay experimenting with this idea and thinking, "When all this is done, where am I going to store this rambling creation?"
