Securing Chainstitches at Seam End:
To secure the chainstitch at the end of the seam, the needle thread need to be pulled through the loop of
the looper thread first and then knotted with the end of the looper thread on the wrong side of the fabric.
> Turn the fabric to the wrong side.
> Undo the loop of the looper thread with a sewing needle and hold it.
> Pull the end of the looper thread upwards so that the loops of the needle thread appear on the wrong
side of the fabric.
> String the loops of the needle threads with a sewing needle and pull them up so that all thread ends are
on the wrong side of the sewing project.
> Knot all thread ends together close to the stitch end.
Securing the Stitches at the Seam End and Detaching the Thread Chain
> Sew the hem or the seam. When sewing in a circle, sew the last stitches over the first stitches.
> Raise the needles and the presser foot.
> Pull the needle threads between the presser foot and the fabric to the back with the CS Lock Tool and
cut them.
> Pull the fabric to the back and cut the looper threads.
– The coverstitches and chainstitches are secured.
– The overlock stitches are secured and the thread chain is detached.
