I thought it was just me who was having this problem and thought I was going nuts or being too particular. I even have a wide backing that was very difficult to square because it didn't seem to be wound very good very full in the center of the backing. I used to love the wide backs for ease of loading and know that it will be smooth through out but the one I have on now I have to keep checking with each roll that it is completely smooth under the quilt. As for the hobbs backing I don't like the packages, they seem to compress the batting so tightly that even with some heat I still have a difficult time getting them to lye flat and even and there have been areas where the batting is very thin in spots. I have also encountered the holes that appear on the back and even with the smallest needle that I could use they just seemed to make it look awful as I quilt. But like Sharon Deming said they do close up after I spray with water and they dry.
