Buttonhole Length
• The buttonhole length should be just long enough to allow
the button to slip through the opening without stretching it.
A. When you use the two-step method of stitching button­
holes, the buttonhole foot will gauge the buttonhole
length for you on most buttons.
B. When button is of an unusual shape orthickness, button­
hole length is not automatically gauged with the button­
hole foot. It is then necessary to adjust the buttonhole
foot. For additional information on adjustment of button­
hole foot refer to page 68.
• To make sure the measurement is correct, cut a slit in a
scrap of fabric equal to the diameter of the button you
intend to use.
• Increase length of opening until button slips through easily.
This test is particularly advisable for buttons of unusual shape
orthickness.
