I love this too. I just finished up 8 T-Shirt quilts. All I can say is trying to stitch through that rubbery stuff (thats on some shirts)...forget it. My machine did not like it at all. Everytime I hit that stuff, the thread would break. I dont know if my machine was being sensative or what. I also ended up using "ball-point" needles, that helped some. I would quilt around some of the designs on the shirts and then of course the borders. Im curious if you used stabilizer on the tshirt fabric? Good luck and I cant wait to see this done. you've done a really nice job.
