The Clear B Edge Stitching Foot guides decorative stitching along an edge perfectly. The tunnel on the bottom of the foot allows stitches to form perfectly and feed flawlessly. The flange along the edge of the foot keeps the distance between the edge of the fabric and the stitching consistent. Anytime your Sewing Advisor or Graphic Display recommends the “B” foot, use the Clear B Edge Stitching Foot when sewing along an edge.
