master of cardboard.

I believe his name is Devin Harrigan aka featherweight and he's your everyday run of the mill cosplayer and I don't think he is a member of the forums though I don't know for sure. But he does a lot of cosplay prop commissions for large range of cosplayers. His website is and he has gallery of different props he makes and there are even tutorial books he makes on prop making some are free and others cost $. His work is pretty amazing considering the attention to detail and only using cardboard to boot just makes his work that much more cooler.

Also he has made quite a few halo props too here is battle rifle made of cardboard
