Hemming
with
the
twin
needle
With
the
twin
needle you can not only embroi-
der
(see page
64),
but
also make
topstitch
seams.
Using
the
twin
needle you can add a profes-
sional touch
to
hems on stretch materials
such
as
T-shirts, knitted articles
or
cycling
shorts both
quickly
and easily. Twin needles
are available in
different
widths. The
traditio-
nal
width
for
topstitching
is
4
mm
. To prevent
the
needle
from
striking
the
needle plate, you
must
make sure
that
you select
the
center
needle position
@)
.
- First fold and iron
the
width
of
fabric desi-
red
for
the hem.
- Then
topstitch
the
hem
from
the
face side.
- Finally, cut
the
protruding
hem edge back
to
the
seam.
Use only a jersey needle when sewing stretch
material!
Tip:
On
difficult
materials such
as
ribbed
knit-
wear
it
is advisable
to
baste
the
hem before
topstitching
it.
On page
64
you will find a description of
how
to
thread
the
twin
needle.

Smocking effect
with
elastic threads
Fine,
light
fabrics such
as
Batist, rayon and
si
lk
are especially suitable
for
beautiful
smok-
king
work
. For smocking
work
with
the
elastic
thread you should use
an
additional bobbin
case and
wind
it
by hand
with
the
elastic
thread. As
the
elastic thread is
much
stronger
than
the
normal bobbin thread,
the
tension
of
the
bobbin
case must be set at very low.
Don't
forget
however,
the
higher
the
bobbin
thread
tension,
the
more intense
the
gathering
effect.
-
Sew
a
test
seam
to
determine
the
level
of
gather
.
-
Mark
the
first
line on
the
face side
of
the
fabric
and sew along it.
- Each additional seam can be sewn at a
presser
foot's
width
from
the
first
row.
-
When
sewing several seams next
to
one
another, you
must
stretch
the
fabric
to
its
original length when sewing
the
subsequent
seams.
Otherwise,
the
gather
will
be
irregu-
lar.
- Knot
the
threads at
the
beginning and end
of
the
seam on the reverse side.
