Singer 1640 - Needle. Thread and Fabric Chart

The
needle
and
thread
you choose
depends
upon
the
fabric
you are
stitching.
The
correct
needle
size is
important
to
avoid damaging
the
fibers
of
light
weight
or
tightly
woven
fabrics
and to
prevent
needle
breakage
when
stitching
heavy
or
stiff
fabrics.

on this
machine.
This style
or
system
is the
most commonly
used on
household
sewing
machines.
•
Always
use
same
type
and
size
of thread
in
both
needle
and
bobbin.
•
Always
use
a
sharp
needle. A
blunt point
can
cause
skipped
stitches
or snag
the
fabric.
Chemical
finishes
and
man-made
fibers
blunt
the
needle
faster.
•
Never use
a
bent
needle.
•
If your
machine
is
skipping
stitches,
replace the
needle
before
looking
for
trouble
elsewhere.
Special
Needles
with
blue
shaft or
ballpoint
are
particularly
designed
to
sew
knits
and stretch
fabrics.
Such
special
needles
can
prevent
sewing
from
skipping
stitches
and damaging
stretch
fabrics.
Available
in size 9, 11,
14 and 16.
