I've made two. Just make sure you have put sabilized the backs, have fun putting the blocks together. The first one I made was for a high school girl that had played ball all her life, so the t shirts were different sizes. I had one row of smaller shirts, and I tried to use even the backs of the shirts if there was something cute on it. I even put appliques on the front and back. She loved it. The next one made used a variety of shirts, from rock concerts and ball games and high school and college. He loved it. They are very time consuming.
