NARROW
AND
ROLLED
HEMS
Narrow
and
rolled
hems
are
ideal
for
use
on
thin
materials
such
as
georgette
crepe,
crepe
de
chine,
silk
etc.
A
narrow
hem
is
formed
by
overlocking
the
fabric
edge
about
2
mm
in
width,
as
shown
in
Fig.
1.
A
rolled
hem
is
formed
by
adjusting
the
thread
tensions
so
that
the
fabric
is
overlocked,
folded
under
and
secured
as
shown
in
Fig.
2.
In
addition
to
the
above
hems,
a
very
pleasing
shell
hem
can
be
produced,
particularly
when
sewing
on
fine
‘scarflike’
materials,
as
shown
in
Fig. 3.
In
view
of
the
nature
of
these
hems,
they
are
unsuitable
for
use
on
‘hard’
or
‘heavy’
materials.
To
make
these
hems
proceed
as
follows:
—
1.
Remove
left
needle
and
use
right
needle
only.
2.
Fit
the
special
needle
plate
and
presser
foot
supplied
in
the
accessory
box
(page
21).
3.
Use
the
appropriate
size
and
type
of
thread
as
suggested
in
the
chart
on
page
22.
4.
Thread
tensions
for
these
types
of
hems
will
differ
from
normal
overlocking,
particularly
with
different
types
of
fabric.
Study
the
recommendations
in the
chart
and
adjust
the
tension
controls
accordingly.
5.
Stitch
length
should
normally
be
between
1 -
2.
6.
Always
test
the
stitch
and
tension
settings
on
a
spare
piece
of
the
fabric
you
intend
using,
before
starting
to
sew
the
actual
garment.
A
narrow
rolled
hems
is
no
problem
when
fabrics
are
prewashed.
With
prewashing
you
will
not
have
to
worry
about
dimensional
changes
or
shrinking,
or
rough
out-side
edges
as
will
occur
on
starched
or
stiff
materials.
