I bought some cheap gauntlets/shin guards from Costumes Etc for about $6 a pop. They are nothing more than flimsy plastic right now, but they have the look I'm going for. The idea is to cut out several layers of foam seal to give them some girth, then pack it tight (heh) and glue it all together. Afterward, spray paint the foam seal so Kratos doesn't have exposed pink anywhere on his body.
Will have to see how this comes together this week...
I glued everything together, and it looked absolutely terrible. Hoo-ray! My next attempt will involve working with leather.
