Marking Lines
Always make a test buttonhoie on a sample of
your fabric. Be sure to duplicate the thickness
of the garment and include interfacing if ap­
propriate.
BUTTONHOLE LENGTH
First decide how long the opening needs to be.
This will depend on the diameter and thickness
of the button. To find the right length, cut a small
slit in a scrap of your fabric and gradually
enlarge it until the button slips through easily.
Then add at least 1/8 inch or 3mm (1/16 inch,
or 1.5mm for each bar tack, the closing at each
end of buttonhoie), and mark the fabric as il­
lustrated. This bar-tack measurement is ap­
proximate; on some buttonholes, you may need
to increase it to arrive at pleasing proportions.

STiTCH WIDTH SETTINGS
Next, determine the two stitch width settings
that you wiii need: one for side stitching and
one for bar tacks. Settings 2% and 5 are il­
lustrated below, although other combinations
may be used, as long as combined widths of
side stitching does not exceed the width of
the bar tacks.
