Looking good. I need to make a Deadshot mask for my upcoming costume. I bought a cheap Deadshot "fancy dress" costume - costume was horrible but it was the mask I was after. I've now put it on a foam head and I'm going to use it as a template for my own. Maybe thin craft foam. Going to grab that pep by Sinner though - always good to have options and that's the first one I've ever come across, so thanks for sharing the link
In the movie will smith actually wears a white open-face balaclava with the mask over the top - that's how they get the effect of the mask covering his whole neck.
