Sew a 2-thread flatlock seam then pull the two fabric layers
apart until the seam lies flat. (fig. A)
Because the threads show on the outside as well as the inside
of the garment or project, the flatlock seam is often conside-
red a decorative application. (fig. B)
For 2-thread flatlock - narrow
1. Lock the machine.
2. Place needle thread on right needle spool pin.
3. Thread needle thread through the upper looper thread guide
on top of the machine, then go down the thread path in the
front of the machine. Go left with the needle thread at the
hook on front of the machine. Then take the needle thread
through the normal needle thread paths. (See illustration be-
low)
4. Engage the subsidiary looper following step 3 on page 13 or
step 5 on page 28.
5. Thread the lower looper as shown in the illustration below.
If you want the "overlock stitching" to show on the right side of
the fabric, place wrong sides together and sew. (fig. C)
To produce the "ladder" (needle thread) on the outside, place
the fabric right sides together.
For a 2-thread narrow flatlock, follow the suggested settings
and threading illustration below.
