The AcuFeed ditch quilting foot is a 9mm foot designed to allow stitching in the ditch. The flange of the foot holds the seam open as you sew, allowing you to easily stitch along its edge. When paired with the AcuFeed flex system, the AcuFeed ditch quilting foot allows you to feed the layers of the quilt evenly as you stitch in the ditch, and the flange of the foot ensures you stay as accurate as possible.
