So any cosplay dorks here? I need help making a shield

[Courage the Cowardly Dog]

I need to make the back. like a handle and such, cardboard and leather belts all handy, maybe I should buy a doorknob and use that as a handle?

How do I secure the leather belt as an arm strap? Duct tape is peeling far to easy.


the backing is cardboard, the front is part aluminum and part tin.
The sides are duct tape.
