Blind
Stitch
Hems
provide
a durable
hem
finish
that is
almost
invisible
and
comparable
with

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

Presser Foot
and proceed
to

The
special
device

so
that this
stitch
just
penetrates
the
fold.. The
frequency
of
the 'throw'
can
be altered
by adjusting
the Stitch

This
may
be necessary
according
to
the type
of thick
ness
of fabric.
