Be sure to use zig-zag foot.
You can make any number of combi
nations by adjusting stitch width and
stitch length.
Both knobs can be
turned while machine is running.
However, if machine is not running,
raise needle to its highest position
before adjusting stitch width knob.
Tension on upper thread usually
needs to be loosened. The wider the
zig-zag,
the
looser
the
tension.
Stitches should lie flat against the
fabric without causing any puckering.
Zig-zag stitching has many uses:
Seam Finishing
Use to "overcast" seam edges in
fabrics that fray to prevent raveling
during wear and washing. Press seam
open and stitch each side separately.
Adjust stitch width and length to suit
fabric. Choose setting that will give
the most open stitch and still secure
the fabric edges. Avoid harsh, over-
stitched edges which become stiff
and show a ridge on right side of
fabric.
Use one of two methods:
• Trim seam edge evenly and place
stitching over raw edge of fabric-
-
best for firmly woven fabrics.
• Place stitching near edge of seam
allowance and trim away excess
fabric after stitching
.
-
best for
fabrics which fray easily, light
weight fabrics, and knits which
roll.
