Baby Lock Evolve (Previous Model) (BLE8W) Instruction and Reference Guide - Manual (Page 39)

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 decora-
tive application (fig. B).
For 2-thread flatlock - narrow
1. Lock the machine.
2. Place needle thread on "OVERLOCK NEEDLE 2" 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 below).
4. Engage the subsidiary looper following step 3 on page 35.
5.Thread the lower looper as shown in the illustration below.
6.Unlock the machine.
Before sewing, select stitch pattern you want to have on the outside of the garment.
For "loops" (lower looper thread) to show, place fabric wrong sides together for sewing the seam (fig. C).
To produce the "ladder" (needle thread) on the outside, place the fabric right sides together (fig. D).
For 2-thread flatlock-narrow, follow the suggested settings and the threading diagram below.
