Would plastic canvas work as a form or "skeleton" under polymer clay? Would it be safe to bake with clay wrapped around it?
My husband plays War Machine and Warhammer. They are table top games using plastic and metal miniatures. I want to make some terrain pieces for him: low stone walls, some taller castle type walls, and eventually a full castle/fortress. The maximum height would be 6-8" for the castle wall and the maximum height for the low walls would be 2-4".
