Looking for suggestions for working with flannel as a backing fabric. i'm making a lap sized 45 x45 baby quilt using flannel as backing. I have a Bernina with a walking foot that I have used to machine quilt small quilts fairly successfully - nothing fancy. This quilt is giving me fits with puckers all over the back. I spent the afternoon quilting and then the evening pulling stitches. I saw one post about flannelquilts which suggested lowering pressure on the presser foot so the flannel doesn't stretch. Does anyone know if this will work when only the back of the quilt is flannel? I'm hoping for some input that will help me avoid another seam ripping session, and let me get this quilt finished and not be embarrassed by puckers in the backing. Thanks in advance!!
