over
spool pins
beforehand.
For
large
cone spools use
the
rubber

the
wide
end
at
the
top, and
for
small
ones,
use
the
same
rubber
spool
holders
but
with
the
narrow end
at
the
top.
SPOOL

When
using
domestic
cotton
reels,
place the
reel
directly
on
to
the
spool
pin.

the spool
cap
to
keep
the
reel
in
place.
SPOOL
NETS

of
polyester
(filament>
thread
or bulk
nylon
thread
are
likely
to
work
loose
from
the
spool
pin
during
sewing, causing
tangling
or
irregular
thread feeding.
To
prevent
this,
use
the
spool
net
provided

keep
the
spool
in
place
as
illustrated,
