/cgl/ - Cosplay & EGL

So I want to remake this belt, since I initially used plastic jars, which were cumbersome and also a little too big. I've thought about using PVC pipe but I have nothing to saw it with, and I feel like craft foam with nothing to back itself would cause it to collapse in on itself.

Putting cans inside is an idea, but no one in this house is a soda/beer drinker, nor eats any canned foods. I might just go with this option anyway and eat like a homeless person for a week, but I'm posting here in case anyone has any other suggestions as to what to make the gold "shells" out of or what to back craft foam with.
