Baby Lock Imagine Wave (Previous Model) (BLE3ATW) 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. 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 below).
4. Engage the subsidiary looper following step 3 on page 25.
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 fab-
ric, place wrong sides together and sew. (Fig. C)
