/cgl/ - Cosplay & EGL

Reposting from the helpoween thread
I'm trying to do a cheap cosplay of balsac from gwar but so far I only figured out how to do the two jaws and how to get them into shape with a wire. i dont know how to set it up so it stays on my head. Some people use a hatbto hold the top part but i have long hair and wanted to use it for the cosplay, and I also want it to be at a wide enough angle so it looks more like the original. What's a good method of setting up a big mask like this?
