The
main
secret*
in producing
a
Blind
Hem is
in the
folding
of
the material,
by following
these
instructions
and diagrams
carefully
you
should
encounter
no difficulty.
If in
any
doubt,
practice
the
*folding'with
a piece
of paper
or
spare
fabric.
Work
with
the 'wrong
side'
of the
Material
uppermost
and
allow
at least
2-1/2"
in
excess
of your
final
desired
length.
It is also
advisable
to choose
a closely
Matching
coloured
thread.
For
these
two Models
it is necessary
to fold
and
place the
material
under
Presser
Foot as
shown

STEP
3. This
is most Important,
With
'wrong side'
still uppermost
open
out again and
bring over
remainder
of
cloth to
for, another
fold on top
of (see diagram)
but approximately
114-
short of your
first fold made
in
Step 1,
STEP
4. With
the
Material
thus arranged
place under
the
Presser
Foot and
proceed
to sew
as diagram.
The special
device in
the Machine
will 'throw'
one stitch
at intervals
and the
Material
must be positioned
so
that this
stitch lust penetrates the fold. The frequency of the
'throw' can be altered by adjusting the Stitch length
lever. This
may be
necessary
according
to the
type
of thickness
of fabric.
STEP 5.
When
complete
unfold Material
and
press flat.
Stitches
should
then be
practically
invisible.
