T-Shirt Quilt!  Each T-shirt quilt is different.  With each one, I like to do the stitching enough so that if they choose to hang for display, The T-shirt fabric won’t sag.  I used a thread that would blend with the T-shirts.  When doing these, important to go over the T-shirts cuz what happens when we wear? They stretch!!  Even with interfacing (sorry, old school), it will break down eventually!
