This thread has been super helpful so far awesome job everyone! I'm making a female Winter Soldier for Free Comic Book Day and this thread has been a God-send for reference images and ideas.
A few things I've found so far:
A mask tutorial:
How I made my Winter Soldier mask - Twins Headquarter It doesn't cover the ears like his, I won't be making my mask to cover my ears cause personally, I just don't want my ears covered. For mine I'm probably going to do something similar to this but using craft foam over the fabric for the front piece and the black/gray pieces. I don't know if this has been mentioned either but I THOUGHT his mask was all one piece including the bit covering the neck but the neck is separate, like maybe a turtle neck or something?
As far as the knee pads I was looking at Home Depot for kneepads but none of the ones I've found have been the right shape so I plan on making them from EVA foam. I got some worbla in yesterday (never used it before it should be interesting!) and I've made a duct tape form of my arm already. I want to make it as seamless as possibly but I'm having trouble figuring out how to do the elbow area and still be able to move XD
His knives I'm actually planning on using pink insulation foam and putting some sort of weight in it so I can flip it around. So far I've only started the jacket I'm starting everything else this weekend, I'll post any useful ideas/pictures I figure out or find!
