SEWING TECHNIQUES
* HOW TO SEW A FLATLOCK DECORATIVE
SEAM
* A ilatlock stitch is achieved by adjusting the
tension of the three-thread overlock stitch, sewing
the seam and pulling the fabric apart to flatten the
seam.
* The flatlock stitch can be used as a construction
and decorative stitch or for ornamentation only.
(1) Machine Set Up
* Remove the left or right needle.
* Begin with the machine threaded and tension
balanced for the three-thread overlock stitch (page

).
* Loosen the needle thread tension (green or blue)
generously.
* Loosen the upper looper thread tension (orange)
slightly.
* Tighten the lower looper thread tension (yellow)
generously.
(2) Flatlocking a Seam
* Place the fabric wrong sides together to sew a
decorative stitch on the right side of the garment.
* Sew the seam, trimming the excess fabric.
* The needle thread (green or blue) will form a V on
the underside of the fabric.
* The lower looper thread will pull into a straight
line at the fabric edge.
