I learned a little trick from a professional longarmer. If the outside edges start to get floppy, he inserts a ruler, or a dowel, even a pencil without a point, into the quilt, on the floppy side or both sides, as he rolls it onto the top roller. Just a short piece. It takes up more room as you roll and tightens up the sides. As for the batting, I would gently tug it over with each turn. There is give in the batting. Good luck. Ann
