POP Mold - Could I? Would you?
Just thinking here. I'm making a POP mold of rhubarb leaf. I have spent $10 in POP for two layers of a very large leaf. Second layer I added cement fortifier to the water and put fiberglass tape in the middle. I was wondering if I needed to do a third layer, and if so, could the third layer be cement (bottom layer)? Has anyone done this?
