I did not post this when I posted the other things that I did with our VBS group this year because it dealt more with duct tape than with anything recycled, but I think that it is worth mentioning as a re-purposing option. I had decided to make duct-tape wallets with our youth because it went well with the VBS race car theme and I could get the tape in the black and white checkered-flag design. The instructions for making them are all over the Internet if you are interested. The ones we made are pictured below.
The problem that I had in trying to do this craft was that I had to have some way of achieving it in twenty-minute segments. This seemed to indicate that it would be better to hand each teen a sheet of duct tape pieces that had already been cut to the correct size. But a sheet of what? I tried the cereal bag plastic that I save and wax paper, but the tape ripped both of them to shreds when you tried to remove it to do the craft. The answer came to me while I was putting contact paper on the place mats. The backing sheet from the contact paper was designed to hold plastic with adhesive on it so why not tape? I tried it and it worked wonderfully! Now I keep some of the backing paper on hand, because I never know when I will need to use to hold duct tape.
