Flowers
Duct tape flowers are the perfect accessory for the duct tape prom night. You can use them as decorations for her hair or for your corsages or boutonnières. Give him and her flowers that will withstand the test of time. All you need is some wire and duct tape in the colors of the outfits that you will be wearing. Simple petals can be made by taking a short rectangular strip of duct tape and folding the top half at a right angle so that the top of the tape meets the side of the tape. There should still be a little adhesive strip at the bottom of the pedal. Just keep adhering the petals together (with the wire stem as a base) in a circular motion using this adhesive strip.
Also try your hand at making bowties, top hats, crowns, cell phone cases, and jewelry out of duct tape.
