I think that also my wig was a wrong Meltdown's wig. I didn't use paper mache and I don't know the name of the product because in Italy is sold as a hobbistic product in specials shops. But they are bandages with a powder of lime on it. To make the mask you have to put the bandages in some water to melt the lime and make them modeled. For modeling I put the wet bandages on a balloon and I shape them. After it's dried I cut the eyes and passed glue as a base for the color. It's easier to do than explain XD
