These two customs stand at 4.5", with a blank Munny as the base to sculpt on. I first cut the "ears" off of the Munny, then cover the openings with a bendable mesh to keep clay from falling inside. I sanded the Munny to allow the clay to adhere to the surface. It's too slick otherwise, and will make it more difficult to sculpt on top of. This was the first time I sculpted, sanded and baked sculpey in layers. If it gets too thick it'll never really harden completely in the oven. Layering ensures a nice tough figure in the end.
