Maybe I missed it, but I don't understand what he wants repaired. Is it just the pictures that need to be replaced? In the picture, it doesn't look like the fabric has worn. Just a another thought, if you can just sew new picture blocks over the worn ones, as someone suggested, you might then restore it more to the original maker's by tying it and not quilting and binding it. It may feel more familiar and comfortable to him that way. And I don't think it is that difficult to transfer pictures to fabric. There is fabric made for that purpose. June Tailor is one brand that comes to mind. This is very nice of you to take on this project and best of luck to you.
