Sensor buttonhole
Patterns number 23 and 25 to 33 are sensor buttonholes.
The size of a buttonhole is automatically set by placing a
button in the rear of automatic buttonhole foot R.
The button holder of the foot takes a button size of 1 cm
(3/8) to 2.5 cm (1) in diameter.
When selecting the sensor buttonholes, the LCD screen
advise you to lower the buttonhole lever.
NOTES:
It is sometimes necessary to change buttonhole size
to match certain heavy or specic fabrics and threads.
Make a test buttonhole on an extra piece of the fabric
to check your settings.
The preset width of the buttonhole is suited for
ordinary buttons.
Apply an interfacing to stretch or ne fabrics.
