HELP. I'm going to Otakon at the end of July, and really wanted to go as Shiro from Deadman wonderland, however I've run into a few problems, especially with her collar. I spent an entire day just drawing out the shape of the collar, and now I'm trying to come up with the best material to make it with that will look as accurate as possible, that is completely doable and not too expensive. Here are some photos of Shiro.
I first thought about using a neck brace and building into it with something....tubing or something. Then I thought about making a fiberglass collar but that's a bit pricey and Im not exactly sure how to work with fiberglass. I was watching a paper mache/sculpting clay tutorial on how to make a dragon on youtube and thought it would be perfect, but I'm not exactly sure what kind of clay was used, so really I would just like some ideas on what I could make it out of. Something that's easy to sculpt, relatively light weight and will hold up well.
