Buttonholes
Sewing buttonholes is very easy
with
all the
models
with
pushbutton controls since the
fabric does not have
to
be turned.
Buttonholes are
generally sewn onto a piece
of
doubled fabric. However,
for
some materi-
als, e.g. silk, organza and viscose, it is neces-
sary to use
silk paper backing
to
prevent
the
material from contracting while sewing.
Avalon (from Madeira) is
ideal
for
this pur-
pose.
It is a special non-woven fiber which
dissolves when it comes into contact
with
water. For materials such
as
velvet
or
thick
woolens, which are
difficult
to
feed, it
can
be
placed over
or
under
the
fabric.
In
this way
the material is not braked and buttonholes are
much easier
to
make.
To produce beautiful
seams, embroidering or
darning threads are
ideally suited
to
this pur-
pose.
Mark
the starting point
of
the buttonhole
either
with
a magic pen or dress pin, and
always sew a sample buttonhole first.
Note:
Before starting any buttonhole, always push
the guide of
the
buttonhole
foot
fully to the
front
, i.e.
so
that
the
red arrow is at the
first
red mark. The red marks are arranged at
an
interval
of
0.5 cm. They are a guide when
determining
the
length
of
the buttonhole.
