I started using Paper Clay to make forms to wrap wires around, I dissolve away the paper and needle felt into the interior. The material, while a bit messy, dries to a nice hard, lightweight consistency that can be filed or sawed. The above picture is the felted wire wrapped form. Afterwards, I thought this material would be good to make a form to coat in epoxy resin. I have been playing with materials to see what works for creating larger pieces.
