On
most
knits,
a
1/4
inch
finished
seam,
such
as
stitch
and
overcast
or
the
overlock
stitch,
is
more
desirable
than
a
5/8
inch
opened
seam
allowance.
These
stitches
can
create
a
neater,
more
profes
sional
finish,
eliminate
bulky
seams,
prevent
curl
ing,
permit
the
garment
to
“give”
under
stress,
and
at
the
same
time
they
cut
down
on
the
amount
of
work
involved
in
making
a
garment.
if
ever
in
doubt
as
to
which
of
the
two
stitches
to
use,
test
both
on
the
particular
fabric
in
question
and
choose
accor
ding
to
their
performance.
The
stitch
and
overcast
stitch
is
excellent
for
stretch
fabrics
such
as
sweater
knits,
bathing
suit
knits,
and
cotton
knits.
It
has
the
greatest
strength
and
elasticity
of
all.
For
patterns
with
1/4
inch
seam
allowances:
Feed
the
fabric
such
that
the
needle
goes
over
the
raw
edge
of
the
fabric
when
it
swings
to
the
right.
For
patterns
with
5/8
inch
seam
allowances:
Feed
the
raw
edge
of
the
fabric
along
the
etched
guide
line
“1/2”,
then
trim
away
the
excess
fabric
close
to
the
stitching.

PROCEDURE:
Overlock
stitching
is
used
for
seaming
and
finishing
the
cut
edge
of
knit
fabrics,
all
in
one
operation.
This
overlock
stitch
is
especially
good
for
stretch
fabrics
such
as
double
knit
and
jersey
and
will
give
a
firm,
neat
edge
finish.
