PLAIN STRETCH SEAMS
When
you
use
the
straight
stretch
stitch
to
sew
seams
in
knit,
stretch,
and
elasticized
fabric,
s-t-r-e-t“C-*h
and
strength
are
built
in
as
the
seam
is
being
sewn.
Because
it
is
equally
use-
fui
for
closed
or
press-open
seam
construc
tion
and
will
not
break
thread
under
stress,
the
stretch
stitch
is
also
good
for
seams
that
re
ceive
an
unusual
amount
of
strain
when
worn.
For
example:
crotch
seams,
sleeve
insertion,
and
construction
seams
in
sportswear
and
bathing suits.
Straight Stretch Stitching
Set stitch control for STRETCH stitching and
use a moderate speed (SLOW speed setting).
Procedure
1.
Make
a
test
sample
to
determine
thread
tension.
Be
sure
to
insert
a
ball-point
(yel
low
band)
needle
in
machine
if
you
are
stitching a synthetic knit fabric.
2.
Stitch
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
$-t-r-e-t-c~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.“

Press
seam
as
when
using
the
regular
straight stitch.
LINGERIE SEAMS
A
narrow,
double-stitched
seam
is
Ideal
for
nylon
tricot

durable
and

the
flexibility
of
the
fabric.
A
regular
stitch
(10
or
12
per
inch)
or
a
stretch
stitch
may
be
used.
Make
a
test
sample
to
help
you
decide
v^hich
is
best
for
your
garment.

with
a
bail-point
(yellow band) needle and fine synthetic thread.
