I guess this would qualify as a home project.
My son wanted to go as RED HOOD... one of Batman's Robins, gone rogue.
The mask was built using a program that prints out shapes on card stock, then you need to cut out the patterns and assemble them into the specific 3D shape you are trying to build (EG: helmets, armors and such)
I used the ol' bondo milkshake and cut down on f-glassing time.
When he gets back from commicon, I'll post the progression of the mask's construction.
