v Flatlock sewing
A flatlock (a) is made by adjusting the tension
of the 3-thread overlock stitch, sewing the
seam and pulling the fabrics apart to flatten
the seam. The tensions must be adjusted
correctly for the fabric to pull flat properly.
A flatlock can be used both as a decorative
construction stitch, sewing two pieces
together (standard flatlock), or for decoration
only on one piece of fabric (decorative
flatlock). There are two ways to sew a flatlock.
Either with the wrong sides of the fabric
together to create a decorative look, or with
the right sides together, to create a ladder stitch.
Standard flatlock, wide (B)
- Use the left needle.
- Thread the lower and upper looper and the
left needle.
- Set the thread tension according to "3–
thread flatlock, wide (and narrow)".
- Place the wrong sides of the two pieces of
fabric together to sew a decorative stitch
on the right side of the project.
- Sew the seam, trimming the excess
fabric. The needle thread will form a V
on the underside of the fabric. The lower
looper thread will pull into a straight line at
the fabric edge.
- Unfold the fabric and pull on opposite
sides of the seam to pull the stitches flat.
Decorative flatlock, wide (C)
- Place the upper cutter in the nonworking
position. The fabric should not be trimmed
on this stitch.
- Follow steps 1-3 above.
- Fold the fabric piece, wrong sides together,
to sew a decorative stitch on the right side
of the project.
- Position the fabric so the seam is sewn with
part of the stitch extending off the fabric.
- Unfold the fabric and pull on opposite sides
of the stitch to flatten.
Tip: The upper looper thread is the prominent
thread in the flatlock stitch. Place a decorative
thread in the upper looper and regular threads
in the lower looper and needle.
