Hey guys I am planning on building an EVA helmet for an Emile costume(Reference picture in my avatar/ profile picture), but before I can get the materials to make it I need to tell my dad the exact method that I plan to use. So far I plan on using this for my guidelines"http://www.youtube.com/watch?v=c1WK26NHx0o&NR=1", however since an EVA visor is larger, and curves around the head I have no idea where to start, and because of it I am at a stand still. Any advice or help on the matter will be GREATLY appreciated.
