strip.
Changing
the
buttonhole
width
For
every
fabric
type,
the
corresponding
button
hole
width
can
be
determined
up
to
5.5
mm.
For
light
materials
select
a
wide
buttonhole
(Fig.

and
a
narrow
one
for
difficult
materials
(Fig.

With
the
stitch

key
(107),
you determine
the
required
buttonhole
width.
The
length
of
