Just last week I was watching a tutorial abt this subject. She took top and folded over front to front, abt half way. Then actually cut the batting in a zig zag way clear across the quilt, (side to side) Then rolled side with no batting toward side with batting, machine stitched that half. Then she sewed the batting back on it's self in a zig zag stitch, Turned quilt around to finish top quiting on the other side. ???? couldn't tell batting was ever cut. So all she ever had rolled at one time was half. :)
