For this exercise, the overlocker will be threaded for a wide
3-thread flatlock stitch using the left needle and thread
colors to match the color-coded threading path on the
overlocker. Adjust all thread tension settings for a flatlock
stitch as indicated in chart below.
Note: If following instructions in the Mastery book,
the right needle was removed in the previous exercise
so you will skip Step 1.
1
.
Using the small screwdriver and needle holder tool,
insert the left needle and remove the right needle.
Tighten the needle set screw after inserting or removing
needles.
2.
Fold the fabric in half, wrong sides together, to 3” x 6”.
3.
Place the fold under the presser foot. Guide the fabric
halfway between the left needle and the right edge of
the stitch finger. This method allows the fabric to lay
totally flat under the stitches.
Optionally, you may choose to trim the folded edge
which will allow one fabric to lay on top of the other.
This is the preferred method if using the flatlock stitch
as a seam.
4.
Slowly sew the fabric. The looper threads will extend
beyond the fabric on the right side of fold.
5.
Gently pull the fabric flat.

Decorative Thread Tip:
A heavy thread such as YLI Jeans
Stitch, Pearl Crown Rayon, or Designer 6 can be used in the
looper for a more decorative look. When working with heavy
decorative threads, loosen the upper looper tension and
lengthen the stitch length as needed for the desired look.
