Buttonhole Length
How long the opening needs to be
depends on diameter and thickness
of button . To find
the right length
1 .
Cut
a small
hole in a scrap of your
fabric and gradually enlarge it
until the button slips through
easily .
7 . . Add at least 1/8 inch (1/16 inch
for each bar
tack, which is the
closing
at each end of the button-
hole), and mark the fabric as
shown .
This bar-tack measurement is ap-
proximate ; on some buttonholes,
you may need to increase it to ar-
rive at pleasing proportions .
Stitch Width
You will
use two stitch width set-
tings : one forthe side stitching and
one for the bar tack . Three possible
combinations are illustrated .
