I really can't tell from the photos if the adhesive was used for the entire quilt or just the one edge of it. My thought in addition to some already mentioned, is that you could just add another backing to it to cover the stained area on the backing....and maybe if you can't fix it ….could any of the quilt be salvaged? Maybe make a smaller quilt out of it for her "dollie" and work on another one for her as she is getting to be a "big girl"? Just some thoughts. I don't use spray adhesive either....but it is because I have asthma. hope it works out. Lin
