Thanks billman,

I hadn't thought of stacking foam like that. That may be a better option, if even for it weighing less.

Does monster mud get heavy?

Edit: The only problem I foresee is how much foam I'm going to have to use. I want it to be 30" high. 2" foam means 15 stacks. 1 sheet of 8ft foam per 2 stacks (4ft diameter) = 8 sheets of foam. At $11 a piece is $88 for just the foam alone. Then the joint compound and paint. I also don't have a blow torch.

I guess not outrageously expensive, but I'd like to hear more ideas. This one, though, has the greatest potential from me being able to create exactly what I want.
