Sewing Overlock stitches For elastic, knits, woven and stretch fabrics, the 2038 and 2048 provides a selection of overlock stitches. These stitches join multiple layers of fabric and overcast them in one operation. These stitches can stretch and are more durable than standard stitches. Tip: Use blind stitch foot No. 3 when sewing overcast seams. This guides the fabric more precisely and prevents tunneling of the seam at wider stitch widths. Adjust the stitch width and guide of the foot to ensure that the right swing of the needle clears the raw edge of the fabric and the pin of the presser foot. Closed overlock stitch - 7 This stitch is suitable for sewing a hem on your garment. Fold your fabric 3/8" (1 cm) and stitch the closed overlock on the right side of the folded fabric. When you have finished, cut away the unnecessary fabric. Overlock stitch - 15 The open overlock stitch works well when joining or edgefinishing fabrics that do not fray excessively. Closed overlock stitch with selvage thread - 18 If you wish to sew a fabric that frays easily, select stitch 18. With this stitch an additional edge thread protects the fabric edge against further fraying. 3:13
