Securing Serged Seams - Bernina Serger Owner's Workbook

Securing Serged Seams

Fabric ....................................................... medium weight cotton, 4" x 6"
Needle ............................................................................. 80/12 Universal
Thread ............................................................... 4 cones of serger thread
.......................................................................... (yellow, red, green, blue)
Presser Foot .............................................................................. standard
Stitch ............................................................................ 4-thread overlock
Thread the serger for a 4-thread overlock stitch. Fine tune the tensions
for a balanced overlock stitch.
Fold fabric in half to 2" x "6" and place under the presser foot. Note:
If you are using a Wavy Rotary Cutter or Pinking Shears to trim the
samples, do all trimming before beginning to sew this sample.
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. Option: 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.
Trim and mount the sample
