What is an overlock stitch?
For stretch fabrics, the select models
offer overlock stitches which sew two
fabric layers together and overcast
simultaneously. They are more elastic
than normal seams, very durable and
quickly sewn.
Tip: We recommend using blindhem stitch
foot No. 3 when sewing overlock seams. It
guides particularly well and prevents the
seam from puckering even on wide seams.
Also remember to set the red marker on the
foot to the right position. This to guide the
fabric edge.

Open overlock stitch
With this stitch, thicker fabrics and fabrics
which do not fray too much can be sewn
together perfectly.
Tip: Make sure that the needle sews to the
right of the fabric just over the edge and not
in it.
Closed overlock stitch
The closed overlock stitch is perfect for
sewing jersey knits. You can also sew
sleeve cuffs and knit collars which are
well-sewn and long-lasting.
Tip: Ensure that the sleeve cuff is stretched
while it is being sewn.
Remember!
When overlocking, if you select stitch
width other than 5 , make sure the
3-5 0/3
needle does not strike the bar of sewing
foot 3.
