Baby Lock Enlighten (BLE3ATW-2) Instruction and Reference Guide - Manual (Page 29)

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 considered a decorative
application (fig. B).
For 2-thread flatlock - narrow
1. Engage the threading lever in the threading position.
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. (illustration below). Thread the right needle for a nar-
row flatlock.
4. Engage the subsidiary looper following step 3 on page 25.
5. Thread the lower looper as shown in the illustration below.
6. Engage the threading lever in the serging position.
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 (fig. D).
For a 2-thread narrow flatlock, follow the suggested settings and
threading illustration below.
