Baby Lock Ovation (BLES8) Instruction and Reference Guide - Manual (Page 36)

Flatlock seams are most suited to fabrics which do not ravel
such as interlock knits, tricot, sweatshirt fleece and synthetic
suede. The needle thread is carried below the fabric and to the
cut edge of the fabric. The lower looper thread rides along the
cut edge of the fabric for stability. The edges pull open and
flatten within the stitch for a non-bulky join. (fig. A) Be sure to
sew a test sample first to determine whether the stitch will have
the strength to hold the seam without the fabric pulling away.
Move the stitch selector lever to "D".
For the O-2 needle 3-thread narrow flatlock, follow the
suggested settings and the threading diagram below.
