I made a huge biker quilt for someone. I ironed stabilizer on the back of the shirts I was going to use, and then I trimmed them up. I had a lot of flannel fat quarters in men's shirt colors. So no mater the size of the t-shirt piece, the squares were all the same. It was king size and very nice. I will try to find a picture of it for you to see soon. I don't think you could make a double sided t-shirt quilt and not quilt over the emblems, because of different sizes on the back and front. I did just large meandering, and it worked very well, and it made the t-shirt material even more stable. I even used the emblems from the pockets.
