I recently did a T shirt quilt for a customer. Included were at least 50 items including T shirts, sweat shirts and even wrestling shorts. One shirt that was dearly loved was almost threadbare. What I did with it was photocopy it onto fabric and then use the copy in the shirt. The wrestling shorts I actually cut out the size piece I was going to use and lined it as it was that kind of shiney nylon fabric with the vent holes all over it. There was even a very faded Leonard Skinner shirt that I actually touched up the color with fabric crayons. Do what ever works best for you. That rubbery stuff that peels off is a pain to work with. Good Luck!
