NEEDLES
The
size
of
the
needle
to
be
used
should
be
deter-
mined
by
the
size
of
the
thread
which
must
pass
freely
through
the
eye
of
the
needle.
Rough
or
uneven
thread,
or
thread
which
passes
with
difficulty
through
the
eye
of
the
needle,
will
interfere
with
the
successful
use
of
the
machine.
(See
chart
on
page
4
to
determine
Size
as
well
as
Class
and
Variety
of
needle
required.)
A bent
needle
may
cause
the
machine
to
skip
stitches,
or
it
may
make
it difficult
for
the
operator
to
keep
o
perfectly
even
margin.
In
many
cases,
a
run-
off will
take
place.
A
hook or burr
on
the
needle
point
will
result
in a
finish
that
looks
blurred
and
when
short
stitches
are
used
(20
to
22
per
inch),
some
materials
may
be
cut.
Check needles
often
to
make
sure
that
defects
are
not
present.
Orders
for
needles
must
specify
the
Quantity
re-
quired,
the
Size
number,
also
the
Class
and
Variety
numbers,
separated
by
an
x.
The
following
is
an
example
of
an
intelligible
order:
"100
No.
16,
88
x
9 Needles."
The
best
stitching
results
will
be
obtained
by
using
needles
sold
by
Singer
Sewing
Machine
Company.
The
above
needles
are
regularly
furnished
with
nickel frnish
but
are
also
available
with
chromium
frnish if
so
ordered.
