When I make a tee shirt quilt, I remember to stabilize the tee shirts first. It is the most important thing to do. I cut the front of the teeshirt at the shoulder and sides leaving it much larger than I want the finished block to be. Then I fuse interfacing (I prefer a light weight Pelon fusable interfacing) to the wrong side of the tee shirt. I place the front of the tee shirt face down on a tefflon pressing sheet and then put the interfacing on the wrong side of the tee shirt and steam it to make sure it sticks very well. Then and only then, I cut the tee shirts to the size blocks I want them to be. Then I add sashings or pieced blocks and put it together how I want it to be. I take it to a long arm quilter to be quilted. i am a hand quilter but I do not hand quilt tee shirts quilts because they just dont adapt well to hand quilting. I hope this helps. You can PM me if you have more questions.
