Have you tried soaking the quilt for a while to really soften the glue before washing? Maybe it is not washing out all the way. Maybe dilute the glue some? The glue could be older and harder to wash out in the initial wash. Just a thought. I have not had that problem either. Just to clarify: You ARE using the Elmer's Washable School Glue, white bottle, twisty orange top.....? Maybe try another bottle. There might be something wrong with your bottle's batch. Hope you find the answer as this glue is so handy for quilting.
