I saw the images of the finished costume and head piece and it looks amazing. I'm wanting to design myself an Alien (Xenomorph)/Human hybrid costume (you know Alien from the world of H.R. Giger).. and so I need to create a head piece shaped a lot like this, sort of a helmet that looks like the heads of the Aliens. Like this for reference, [link]
It wont be quite that long, but the important thing I know I have to keep in mind is to keep it light weight. It looks like you mostly used mat board/cardboard paper to shape yours. I might be using craft foam for mine. But my question is, how did you keep it from falling off your head? Did you attach a headband underneath or something else to get it to stay? Any tips on how to keep it weighted so it doesn't just fall off the back of my head? Thanks!
