Singer 645 - Overlock Application

.
OVERLOCK
APPLICATION
Special
ultra-stretch
stitches
are
also
very
usable
for
overlock
stitching
on
both
woven
and
knit
fabrics.
(A) Place
the
raw
edge
of
the
fabric
under
the
presser
foot
so that
as the
needle
swings
to
the
right,
it
comes
down
at
the
raw
edge.
This
will
result
in
an
enclosed
seam
allowance.
(B)
The
seam
allowances
may
be
trimmed
to 1/4
inch
either
before
or
after
sewing.
If
trimming
before
sewing,
proceed
as
above.
Otherwise,
sew
the
seam
with
the
raw
edge
of
the
fabric
on
the
etched
guide
line
1/2”.
(Any
time
you
use
the
full
width
of
a
particular
stitch,
you
should
readjust
the
raw
edge
of
the
fabric
1/8
inch
to
the
left.)
Afterward,
trim
the
excess
fabric
near
the
stitching.
This
method
is
actually
easier
than
the
overedge
method
for
fabrics
that
curl.
Note:
On
soft,
loose
knits,
the
fabric
may
seem
to
wave
or
ripple.
If
this
occurs,
reduce
the
pressure
on
fabric.
