Thread the chain through a large eyed needle, and weave that chain through the overlock stitches
on the fabric.
Backstitching
To avoid unravelling, it is necessary to leave a thread chain about 5 cm (2") long at the beginning and
end of seam. To secure the beginning and end of a seam choose one of the following methods.
At the beginning
Before putting your fabric in the machines, sew a thread chain about 5 cm (2") long behind the
needle.
Put your fabric in the machine. Then serge a few stitches and stop.
Raise the presser foot and bring the thread chain to the left around and under the presser foot.
Place the thread chain between the presser foot and upper knife, holding it in position as you
lower the presser foot to sew.
After sewing about 2.5 cm (1"), move the chain to the right and under the upper knife, cutting the
chain as you sew.
Serge one stitch off the end
of seam.
Raise the needle and presser
foot, and gently pull the
threads off the prong.
Turn the fabric over so the
under side is up.
Serge about 2.5 cm (1") over
stitching and angle off the
fabric.
