Knit stitch

Machine settings
q Pattern:	11 (mode 2)
w Presser foot:	Zigzag foot A
e Thread tension:	AUTO

This stitch is recommended for sewing such fabrics as synthetic knits and stretch velour, as it provides the greatest amount of elasticity and strength.

Sew along the fabric edge leaving an adequate seam allowance.

After sewing, trim the seam allowance close to the stitches.

Double overedge stitch

Machine settings
q Pattern:	12 (mode 2)
w Presser foot:	Overedge foot C
e Thread tension:	AUTO

This is an excellent stitch for fabrics that tend to ravel extensively such as linens and gabardines.

Two rows of zigzag stitches are simultaneously sewn over the edge to insure that fabric will not ravel.

Place the fabric edge next to the guide of the foot and then sew.

CAUTION:

When you use the overedge foot C, you must set the zigzag width at 5.0 or wider to prevent the needle from hitting the wires on the foot.

Overlock stitch

Machine settings
q Pattern:	13 (mode 2)
w Presser foot:	Overcasting foot M
e Thread tension:	6–8

This stitch finishes the edges of fabric similar to a commer- cial overlocking machine for a professional look.

Place the fabric edge next to the guide of the foot and then sew.

CAUTION:

When you use the overcasting foot M, you must set the zigzag width at 5.0 or wider to prevent the needle from hitting the wires on the foot.
