1. Mark position and length of buttonhole on fabric.
2. Open the slider on the foot. Set the button on the base of
the foot.
Adjust the slider to the diameter of the button, so the
button fits snuggly in the foot.
For buttons with an irregular shape that do not fit snuggly
in the Buttonhole Foot, remove the button from the base
of the foot. Adjust the slide on the base to the diameter of
the button, plus the thickness of the button.

bring upper thread to the left.

mark is in the center of the Buttonhole Foot.
Lower the foot while pulling the frame of the Buttonhole
Foot towards you.
NOTE: It is suggested that you use interfacing on the backside
of the fabric.
