X. BUTTONHOLES
Various fabrics require various methods of sewing 83
buttonholes. Four different methods are given
below, with suggested uses. If you are in doubt as
to which method is best for your fabric, test the
methods in question and choose the best according
to the finished appearance.
PREPARATION
For the best results, a good quality mercerized
cotton thread should be used. Polyester threads
often result in puckered or heavy unattractive
buttonholes. The finer your fabric is, the finer
your cotton thread should be. An interfacing
should be used under the buttonholes to give body,
34
to strengthen, and to help them withstand wear.
To establish the correct length of the buttonhole,
add the diameter of the button (A), plus the
thickness of the button (B), plus 1/8 inch for the
bartacks. (Fig. 83) The length may be marked on
the garment with a basting stitch, tailors chalk, or
transparent tape, as shown. (Fig. 84) Another way
to make sure that all buttonholes will be the same
size is to cut a piece of cardboard as wide as the
buttonhole foot and long enough to make the
distance between the toe of the white slide and the
cardboard
the
size buttonhole needed. This
method works for buttonholes up to

inches
long. Horizontal buttonholes should extend 1/8
inch beyond the center line of the garment. (Fig.
85) Vertical buttonholes are placed so that the
cutting space of the buttonhole is directly on the
center line. (Fig.
86
) Always make a practice
buttonhole on a scrap of the garment fabric before
making any buttonholes on your garment. On
your test sample, duplicate the thickness found in
the garment and be sure to include the interfacing.
The test sample should help determine the length
needed for the button to pass through easily,and
the stitch length for the particular fabric. As with
the satin stitch, the stitches should be close
together, but not so close that they pile up. Be
86
sure to use the buttonhole foot.
