3-Thread Flatlock Stitch

Fabric: Firm fabric, 6” x 6”

Needle: 80/12 Universal

Thread: 3 cones of serger thread (blue, red, yellow)

Presser Foot: Standard

Stitch: 3-thread Flatlock

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.
