Chain Stitch
This stitch is sewn with a single needle 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 (see page 8).
NOTE:
Tighten the needle clamp screws on the sides that are
not being used to prevent losing the screws.

the tension as necessary.
