and
insert
a
twin needle (which
can be ob

from
your
Pfaff dealer).
Stitch length:
1.5 to 2.
Cording is made with two
needle threads.
When
threading
the needles, make sure
to
lead
each thread
between
a separate
pair
of
tension
discs
(see
ill.).
To render
your
cording
more
prominent,
in

a
filler
cord. Select the
twin needle
gauge
and the size of the filler
cord to suit
the
type of
material
used. The thicker the
fabric
the wider the
needle
gauge.
Lace the filler
cord through
the hole in the
needle
plate,
as
illustrated.
Hold
both needle threads
lightly
and
turn
the balance
wheel to draw up the bobbin
thread.
The
smallest
distance
between cording
seams
made with
the
ordinary
sewing
foot
is
approx.
inch. For narrower cording,
use one
of the
cording
feet
listed below.
