Decorative Chain Stitch
Following the instructions in your owner’s manual, thread the serger for
cover stitch, threading the 3 strands of Isacord embroidery thread
together, treating them as one thread. Use a lower looper threader or
dental floss threader to thread them through the eye of the looper.
Slightly loosen the tension on the chain stitch looper.
Place the stabilizer against the wrong side of the denim. Place the
denim right side down under the presser foot; the stabilizer will be on
top.
Chainstitch a curved line across the fabric. Turn the fabric over to see
the decorative stitching on the right side.
To increase the amount of decorative thread that shows, increase the
stitch length to 3mm or 4mm. Changing stitch length as you serge will
vary the decorative chain stitch effect. Always use a stitch length of at
least 2.5mm.
Stitch several more curved lines across the fabric.
Remove one spool of Isacord embroidery thread and replace it with
Yenmet metallic thread. Rethread the serger using 2 spools of Isacord
embroidery thread and 1 spool of Yenmet metallic thread in the lower
looper. Loosen the chain stitch looper tension slightly. Sew several
additional rows of decorative chain stitch.
Trim and mount the sample.
