I would probably want it to be about a foot tall, maybe less than that. I would like a fair amount of detail. I was thinking of forming a wire mesh cage, paper mache over that to get the basic shape, then applying air dry clay over the top for the details, especially in the face.
I want to be able to put it outside in my flower garden.
I know polymer clay needs to be baked. But does anyone recommend a brand of clay that air hardens? I'd like to make a lawn gnome but I probably couldn't bake it. I don't want to buy a mold and pour cement into it. I want to make a gnome myself. Would air hardening clay be weather resistant? Should I seal it with varnish?
