I used them to hold up my leg warmers, keep my knees warm, carry my flashlight, work on my bike, for decoration, hold my elwire inverters, and as a topic of conversation because everyone asks what they're for

try duck tape, it now comes in a variety of colors. See post under topic "transform your clothes/shoes"

I have made some of the best costumes out of old party and holiday decorations that would have been thrown away. Since duck tape now comes in every color, it's the perfect thing to put your mylar and plastic costume together. It's super cheap, always unique, and you can burn it when you're done.

Once you have your $3.00 thrift store knee pads at burning man, you'll wonder what you ever did without them!
