Thanks for the answers!
The quilt is nearly finished and the shirt is already in, and quilted. It was necessary to the balance of the whole thing, and is of significance to the client. The amount that is peeling up is mostly at edges of breaks in the "film", and not at the edges of the whole image. I was extremely careful not to introduce more holes (by quilting over it) than was necessary to stabilize that square. What I had been thinkiing was to take something like Krazy Glue and dab a tiny bit on the tiny edges that have risen. I was hoping someone would reply to this thread with "Oh yes - here is the name of a permanent fabric adhesive designed for gluing down T-shirt images, and it is on sale this week at JoAnn's."
