In anticipation to the release of Star Wars VII, I thought that it would be pretty ambitious if I made a Togruta Jedi costume. My only problem is the headpiece. I am allergic to LATEX. What materials should I use that would give the head tails flexiblility but the montrals (horns) rigid and sturdy enough to stay on my head but not too heavy? Another issue is my hair; it's too long to put up without the headpiece looking bulky and misshapen. How can I make the head tails hollow in order to put my hair into them?
