Securing Serged Seams

Fabric: Firm fabric, 6” x 6”

Needle: 80/12 Universal

Thread: 4 cones of serger thread (blue, red, green, yellow)

Presser Foot: Standard

Stitch: 4-thread overlock

Thread the serger for a 4-thread overlock stitch using thread

colors to match the color-coded threading path on the serger.

Adjust all thread tension settings as indicated below.

Fold fabric in half to 3” x “6” and place under the presser foot.

Take 2-3 stitches on the fabric. Lower the needles into the fabric.

Raise the presser foot and with your left hand gently pull the thread

chain around the needles to the knife.

Lower the presser foot and continue serging (cutting off the excess

thread chain) until you are one stitch off the end of the fabric.

Locate the Stitch Selection lever on the right side of the cloth plate;

pull it towards you, releasing the thread chain from the stitch

tongue.

Raise the presser foot and carefully flip the fabric over so that

the lower looper side of the previously serged seam will be

overstitched.

Place the fabric under the presser foot so that the first stitch will

enter the fabric when you begin stitching.

Slide the Stitch Selection lever towards the body of the serger.

Serge for about 1”, overstitching the previous stitching. Guide the

fabric so as not to cut the previous stitching. Optional: Rotate upper

knife up.

Raise the toe of the presser foot and rotate the fabric 90° clockwise.

Serge off the edge of the fabric.

If the upper knife is up, rotate it down into the cutting position.
