I'm making a costume for my horse for a show we are doing in August.
I'm making my horse into a moose. I need to make his antlers, and I know they need to be really big. I was thinking about using just regular craft foam, but I don't think that will hold its shape and will flop around. What else could I use? I was thinking maybe styrofoam, like the stuff that comes in sheets that people use as temporary insulation, but I don't know.
Any ideas? It needs to hold its shape, not flop around, and be lightweight.
