I'm making an ENA cosplay for Halloween, and I want to make the low polygonal arm out of EVA foam. I've made armour parts before, but due to the shape of the arm, I'm a bit stuck on how to go about it. Mainly, how to make it in such a way that it will stay on my arm, and how to make the joint section look good. The glove section as well I'm unfamiliar with. Any advice is appreciated!
