Sewing sensor buttonholes
Buttonholes 11 and 13 to 17 are
sensor buttonholes.
The buttonhole size is automatically determined by placing
a button in the foot.
Buttonhole Tips
The button holder of the foot takes a button size of 3/16”
(0.5cm) to 1” (2.5cm) in diameter.
It is sometimes necessary to change the buttonhole’s size
to match fabric, button size and threads in a project.
Make a test buttonhole on an extra piece of the fabric
to check your settings. If the buttonhole size needs
adjustment, just increase the distance where the button
sits in the foot.
For best results when sewing buttonholes, use a stabilizer.
Simply add a tear-a-way stabilizer on the back side of the
fabric when sewing buttonholes.
How to sew
This buttonhole is widely used on medium to heavy weight
fabrics.

Size of button
If the button is extremely thick, make a test buttonhole on
an extra piece of the fabric to confirm the button will pass
through the buttonhole opening.
If it is difficult to fit the button through the test buttonhole,
you can lengthen the buttonhole by pulling the button
holder back a little. The length of the buttonhole will be
increased.
