ATTACHING ELASTIC To Attach Waistline Elastic
Elastic wiii remain stretchable when it is
attached with the plain zig-zag stitch. The
flexible joining
proQuced
by this stitch allows
elastic banding to be stitched under, oven or
between
fabric layers, making it particularly
useful in the construction of lingerie and swim
suits.

Attaching Elastic with Zig-Zag Stitch
1. Fit elastic for desired waistline snugness,
allowing one inch for joining. Lap ends and
join with zig-zag stitching.
2. Divide elastic band and
garment
waistline
into
quarters or
eighths. Place elastic over
fabric and pin the two
together
at these
points.
3. Take a few stitches to anchor elastic to
fabric, then stretch elastic between pins as
you sew,
using
both hands to hold elastic
taut In front and back of the presser foot.

When you use the straight stretch stitch to
seam
knit, stretch, and elasticized fabric,
s4-r-e-i-c-h and strength are built in as the
seam is being sewn. Because it is equally use­
ful for closed or press-open seam construc­
tion and will not break
thread under
stress, the
straight stretch stitch Is also good for seams
that receive an unusual amount of strain when
worn. For example: crotch seaming, sleeve
Insertion, and construction seams in sports­
wear and
baling
suits.

Stretch Stitching
1. Make a test sample to determine thread ten­
sion. Be sure to insert a bail-point (yellow
band) needle in machine if you are stitching
a synthetic knit fabric.
2. Stitoh and guide fabric as you do for plain
seams stitched with the regular straight
stitch, letting the machine make the back-
and-forth
stitches that give s-t-r-e-t-o-h to
the seam. If fabric has an unusual amount
of
elasticity, it should be stitched under
tension as instructed under "'Guiding and
Supporting Fabric.”
3. Press seam as when using the regular
straight stitch.
