Overlock stitches
For elastic, knits and stretch fabrics, the 2034 and 2044 provide a selection of overlock stitches. These stitches join multiple
layers of fabric and overcast them in one operation. These stitches have built-in stretch and are more durable than standard
stitches.
Tip: Use blind stitch foot No. 3 when sewing overlock 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-hand swing of the
needle clears the raw edge of the fabric and the pin of the presser foot.

This stitch, in a single operation, is suitable for sewing and
serging fabrics that fray easily. The closed overlock is also a
good stitch for attaching knit cuffs and collars to garments.
If you wish to sew a fabric that frays easily. select stitch 21.
With this stitch an additional edge thread protects the fabric
edge against further fraying.
The open overlock stitch works well when joining or edge-
finishing fabrics that do not fray excessively.
Used together with the knit-edge foot (special accessories),
this stitch can be used for open-knit and heavy knit fabrics.
Garments can be joined effortlessly with this stitch.
Tip: To prevent the seam from stretching while sewing,
overcast a woolen thread or twill tape in the seam.
