I made the spring out of a little piece of silver wire that I wrapped around a pen to get the shape. I sandwhiched green craft foam around one side of it and stuck the other side down inside the hood and hot glued it in place with some more craft foam on the inside. I made a lump of hot glue on the outside at the base of the spring that I painted silver to get the finished look.
Um... scroll down in the comments. I think I explained it a few different times there. It wasn't that hard. I just bought the grey pieces, underwear, and mask from places like Walmart and JoAnn's and altered them and made the hood/cape out of a sheet. It is best to take full color pics of the character with you when you go shopping.
I don't mind at all. I explained in detail somewhere down on the comments a couple of times actually, but basically I bought the grey pieces, gloves, underwear, belt, shoes, and mask at places like Walmart and JoAnn's and altered them. I used an old sheet to make the hood and cape. It is best to take a full color printed picture with you when you go shopping so you can make sure to get all the right pieces.
The cape actually wasn't too hard at all. I folded it in half and cut the hood on the fold from the center at the top. I was left with a long rectangle with two strips on the sides. I wrapped the strips around my neck and safety pinned them, sewed one seam in the middle of the hood and turned it, and hot glued the question mark in place after pulling through a hole in the top. Someone who didn't sew could probably just fold part of the sheet over their head in a hood shape and wrap some blue material around their neck over it like a scarf and pin it in place to hold the hood shape and cape in place.
