I would make a list of the various ways you could fix the quilt. Then have a meeting with the young man who asked you to fix the quilt. Let him make the decision and then fix it the way he wants. If he still wants the original pictures, I would make a wall hanging quilt with the new pictures on it so he can use the quilt and look at the pictures at the same time. I would include that in the list of choices you give him. Good luck
