Three kinds
of
buttonholes
can
be
sewn,
viz.
braided
buttonholes,
buttonholes
with inlaid
thread
and
buttonholes
with
raised
stitches"
The
two
first
types
of
buttonhole
are
sewn
with
weak tension
of
the
upper
thread,
with No.
40
darning
thread. For the last type, a
Yery
weak tension
for
the under
thread
should
be
used,
while
the
upper
thread
should
be
so
tight that
the
under thread
is
visible
on the
upper
surface
of the
cloth.
A No. 40
6-twist
thread
is
recomrnended
for

type
of
