Buttonholes
Buttonholer
When you wish to sew a keyhole buttonhole close to a
faced edge, use the buttonholer. Attach presser foot A or
B. The buttonholer fits in under the presser foot—use
the edges as a guide.
Mark the positions of the buttonholes with pins or
basting thread. Insert the fabric under the presser foot
and allow the needle to pierce the fabric at the foremost
pin.
Push the buttonholer in under the presser foot until
the space between its foremost part and the front edge
corresponds to the seam allowance. Lower the presser
foot and sew the buttonhole in the usual way. Start the
rounded part sufficiently far from the edge so as to avoid
the rounded end extending outside the marking.
Cutting the buttonhole
The buttonhole knife which you will find in the acces­
sory box, is equipped with a safety cap which, when
taken off, can be pushed onto the back of the knife,
providing a longer handle.
Cut the buttonhole as follows: Pierce the fabric at a
right angle until the curved blade edge reaches down to
the buttonhole.
With the knife more or less parallel to the fabric, push
forward, taking care not to cut the columns of the
buttonhole. The small red bead serves as a guide. Cut the
buttonhole to the middle and repeat the cut from the
other direction.
