I am quilting a baby quilt - top is all cotton, batting is Warm and Natural, backing is a light flannel. I am using a walking foot and notice that the imprint of the walking foot is on the backing. I lengthened my stitches and decreased my presser foot, but the imprint is still showing. I called the Bernina shop, and they said to not worry that this is normal and the imprint will wash out. I think it will wash out too, but I am just wondering if anyone else has noticed the imprint when using the walking foot.
