Sculpting material for thin walls
I've been given a beautiful piece of drift wood and I'm hoping to create a sculpture incorporating my children in a white and gold leaf hoop.
I'm trying to create a cylinder about the dimensions of a car tyre but with very thin walls. I'd like it to look like white ceramic but would be OK to paint it white. It needs to be airdray as it's too large for the kiln and would prefer it to be waterproof but that's not essential.
Can anyone recommend a material that wouldn't crumble or be as brittle as ceramic but would give the same look? I have been looking at some light weight foam airdry clays as they seem to be spongy (although regular airdry clays have fibres, they still tend to be too brittle).
Perhaps I could use a wire mesh frame that I cover with the material?
Any help would be appreciated.
Also, I'm in the UK so hoping
Thanks in advance
