I'm trying to make a non-Fett helmet and costume for Halloween but am having two main problems:
1. How to shape the dome? I'm not sure the best way to go about this - do I need to make a template somehow? The helmet will actually be considerably larger than my head, about 15-16" diameter (50" circumference).
2. The body portion of the costume is basically one large cylinder shape, 25" diameter (78-80" circumference). Since this won't fit in my oven, how do I heat it up for molding? Do I need to cut it into smaller pieces and then re-assemble?
Any assistance for my first DIY costume w/ sintra would be much appreciated!
