Overlock stitches
For elastic, knits, woven and stretch fabrics, your creative 2170
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 – No 26
This stitch is suitable for sewing a hem on your garment. Use foot no.
0A or 3.
Fold your fabric 3/8” (1 cm) and stitch the closed overlock on the
right side of the folded fabric. When you have fi nished, cut away the
unnecessary fabric.
Open overlock stitch – No 28
The overlock stitch works well when joining or edge-fi nishing fabrics
that do not fray excessively. Use presser foot no. 1A or 3.
Closed overlock stitch with edge thread – No 19
If you wish to sew a fabric that frays easily, select stitch no. 19. With
this stitch an additional edge thread protects the fabric edge against
further fraying. This seam is suitable for woven fabrics.
