Firm fabric, 6" x 6"
Fabric:
80/12 Universal
Needle:
3 cones of serger thread (blue, red, yellow)
Thread:
Standard
Presser Foot:
3-thread Flatlock
Stitch:
Using the small screwdriver and brush/needle insertion tool,
remove the right needle. Snug the needle set screw after
removing the needle.
Thread serger for a wide 3-thread flatlock stitch. Adjust all thread
tension settings as indicated below. Note: Sample was stitched
with regular thread but a heavy thread such as YLI Jeans Stitch
or Designer 6 can be used in the upper 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.
Fold the fabric in half, wrong sides together, to 3" x 6".
Optional: Attach the Right Seam Guide to the serger (700D and
800DL will require the Attachment Base). Move the Right Seam
Guide halfway between the needle and the stitch finger.
Place the fold under the presser foot. Guide the fabric halfway
between the left needle and the right edge of the stitch finger
(or against the Right Seam Guide).
Slowly serge the fabric. The looper threads will extend beyond the
fabric on the right side of fold. Decorative Thread Tip: To avoid
uneven stitches, tangled threads, hiccups, and other imperfec-
tions, always serge slowly when working with decorative threads.
Gently pull the fabric flat.
Return stitch length
and thread tension
levers to their normal
settings.
Optional: For a narrow
flatlock stitch, reset the
serger using the right
Needle.
