Needle:
80/12 Universal
Thread:
4 cones of overlocker thread (blue, red, green, yel-
low)
Presser Foot:
Standard
Fold fabric in half to 3" x 6".
Using a fabric marker, divide the fabric into four equal sections
along the folded edge.
Thread the overlocker for a 4-thread overlock stitch using thread
colors to match the color-coded threading path on the overlocker.
Adjust all thread tension settings as indicated below.
Adjust the stitch length to 4mm. Sew to the first mark along the
folded edge, trimming the fold slightly.
Adjust the stitch length to 3mm and sew to the second mark.
Adjust the stitch length to 2mm and sew to the third mark.
Adjust the stitch length to 1mm and sew to the end.
Mark the stitch length settings on the fabric sample.
Return stitch length to its normal setting, 2.5mm.
Stitch length adjustments may be needed to accommodate
thicker or thinner threads or different weights of fabric.
General guidelines for stitch length settings:
1-1.5mm: rolled hems and decorative edges
2-2.5mm: seaming and general overlocking
3-4mm: certain techniques such as gathering
and applying elastic
