What is an overlock stitch?
For elastic materials and knits, the hobby
1142 offers an overlock stitch which sews
two fabric layers together and overcasts
simultaneously. It is more elastic than
normal seams, very durable and quickly
sewn.
When sewing overlock seams, use
overcasting foot C. It guides particularly
well and prevents the seam from
puckering.

Open overlock stitch

With this stitch, thicker materials and
fabrics which do not fray too much can be
sewn together perfectly.
This stitch seams and nishes the fabric
edges simultaneously.
Place the edge of the fabric next to the
guide of foot and sew while guiding the
fabric edge along the guide.
Tip: Make sure that the needle is just off the
raw edge of the fabric and not into it, when
the needle swings to the right.
Note: Do not set the stitch width less than 5
when using the overcasting foot C, otherwise
the needle may hit the foot causing the needle
to bend or break.

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 a needle
position other than center,
stitch width other than 5, make sure the
needle does not strike the bar (A) of the
overcasting foot C.
