I made 5 t-shirt quilts last year for my son and some of his fraternity brothers. I used tricot fusible web for the tee shirt squares. It gives a little with the tee shirt and isn't stiff. I also used fleece for the backing and didn't have to use batting that way. After the squares are sashed and sewn together I quilted free motion with a randon pattern. Hope this helps. Also, I got the web at Joanne's.
