My DIY Pokemon party table covers. $1 store white plastic table cover, red plastic cover, black duct tape, and a paper plate. I folded the table covers in half, then taped them together with the duct tape. I put more duct tape around a paper plate to make the button, but they looked fine without the button also.
Pretty Gamer: How to - Make Batman's utility belt out of yellow duct tape. Awesome idea! I'd want to try lining the pouch bottoms with cardboard or flexible plastic to see if it could actually hold stuff.
