In one of the last Quilters Newsletter the cover photo had a quilt that had framed blocks in white, etc. They were very narrow. She said that in order to get the quilt like that she used glue too. Oh, on the batting, try using the scraps of fuseable. I took a class where the lady used lots of the stuff and you always end up with lots of scraps. Those scraps would be collected and then sprinkled on the backing and then on the batting. Hope this might help. I think that the glue on the back may be having the same problems as gluing on paper. The moisture causes the fabric to act like paper (both cellulose, and buckle) you might be asking too much of the glue done in that way. If you could try to make it aerosol. Maybe try adding water to a spray bottle and mix the glue with it. Kind of 50/50--or what the aerosol pump can handle.
