U10 U12 U13 U9 U11 31 Variety of overcasting stitches U9 Multiple zigzag stitch (tricot stitch): Zigzag foot A This stitch is used to finish a raw edge of synthetics and other stretch fabrics that tend to pucker. Sew along the fabric edge leaving an adequate seam allowance. After sewing, trim off the seam allowance closer to the stitches. U10 Overcasting stitch: Overedge foot C This stitch can be used to simultaneously seam and overcast edges of fabrics. Use this stitch when you do not need to open seams flat. Place the fabric edge next to the guide of the foot and then sew. U11 Knit stitch: Zigzag foot A This stitch is recommended for sewing such fabrics as synthetic knits and stretch velour as it provides the greatest amount of elasticity and strength. Sew along the fabric edge leaving an adequate seam allowance. After sewing, trim the seam allowance close to the stitches. U12 Double overedge stitch: Overedge foot C This stitch is excellent for fabrics that tend to fray extensively such as linens and gabardines. Two rows of zigzag stitches are simultaneously sewn over the edge to insure that the fabric will not ravel. U13 Overlock stitch: Ovrecasting foot M This stitch finishes the edges of fabric similar to a commercial overlocking machine for a professional look. CAUTION: When you use overedge foot C or overcasting foot M, you must set the zigzag width at 5.0 or wider to prevent the needle from hitting the foot wires.
