STITCH VARIATIONS AND
SEWING TECHNIQUES
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.
• Machine Set Up
–
Use either overlock right needle or overlock left
needle.
–
Begin with the machine threaded and tension
balanced for the 2-Thread flatlock stitch (refer
page 45) or 3-Thread flatlock stitch. (Refer page
47)
• 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 (yellow or green) will form a
V on the underside of the fabric.
–
In the 3-thread flatlock, the lower looper thread
will form a straight line on the fabric edge. The
upper looper thread will lie on top of the stitch.
–
In the 2-thread flatlock, the lower looper thread
will lie on top of the stitch.
–
Pull on opposite sides of the seam to pull the
stitches flat.
