>>201524I've made Canti helm 3 times. First time support was with news paper, next one was cloth, and the last one I went as far as using spray foam (which hardened it just fine), but still ended up warping.
I don't want cardboard, because I'm not making a Gundam.
All in all, I'm about two seconds away from calling it quits, and about one second away from making a vaccuforming machine.
And before someone goes off on me on a tangent saying cardboard will be the best thing: I made the body piece from it (thinking it'd be best for the body), and the results there weren't pretty (many frustrating hours to make a ghetto-rigged body piece)
