Chain Stitch
This stitch is sewn with a single needle and two threads
and forms a chain of looper thread on the wrong side of
the fabric.
This is a durable and flexible stitch used for seaming knit
fabrics, attaching elastics, attaching bias tapes, etc.
Thread one of the three needles and looper. Remove the
needles not to be used (refer to page 10).
