I have been working on a project using clay that involved a lot of stamping. I ended up with some clay that was off cuts of stamped imaged and really unusable in its original colour. So I rolled it up and used it in moulds. It has got a nice marbled effect to it now and suits the moulds I have used it in.
These are my Clay Babies for use on larger projects, made with a selection of different parts of moulds and rubber stamping. They still need finishing (sanding and maybe a bit of colouring)
