BUTTOMHOLE LENGTH
A buttonhole length should be just long
enough to allow the button to slip through the
opening without stretching it,
« Estimate the proper buttonhole length by
measuring the width plus the thickness of
the button.
o 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 or thickness.

BUTTONHOLE INTEHFACING
It is almost always advisable to use an inter
facing in the buttonhole area. An interfacing
holds the fabric firmly so that a neat but
tonhole may be stitched and keeps the
finished buttonhole In shape, interfacing is
essential when the fabric is loosely woven or
is a crepe or knit that stretches easily.
When planning your garment, remember that
bar tack buttonholes are stitched through
three thicknesses of fabric — garment, inter
facing and facing —after the facing has been
attached.
