I have seen a few displays at the LQS where they made a regular quilt, like with just patchwork squares, but some of the squares had pockets made of the clear plastic stuff (vinyl?) that you would cover furniture with. This way a photo could be changed out, or removed for cleaning. It was a neat idea.
