How to Sew a Flatlock Decorative Seam
A flatlock stitch is achieved by adjusting the tension
of the 2-thread or 3-thread overlock stitch, sewing the seam,
and then 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
Use either overedge right needle or overedge left needle.
Begin with the machine threaded and tension ATD-E
balanced for the 2-thread overedge (page 42) or
3-thread flatlock stitch ATD-F (page 44).
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 (orange or blue) will form a V on the
Needle thread
underside of the fabric.
The lower looper thread will pull into a straight line at the Upper looper thread
fabric edge.
