I made a t-shirt quilt using the fronts of the shirts for the front and the backs for the back. It came out great. Of course I stabilized all the t-shirts, and I even used small leftover pieces of the shirts for fillers, and borders. I used a thin batting, and it turned out to be a very heavy quilt. My grandson loves it! I had no trouble machine quilting it, except for the rubbery logos on the shirts which I learned (from this board) to quilt using tissue paper so that the presser foot didn't stick.
