BUTTONHOLES
Various widths and lengths can be made automatically by turning
the dial. "25" {Fig. 1).
To establish the correct length buttonhole required add 1/8 inch
to the cutting space for bar tacks.
To obtain the length of the cutting space, the opening through
which the button passes, is measured by adding the width (A) and
thickness (B) of the button. {Fig. 41)
The width of the buttonhole sides is governed by the material
used.
Set zigzag width lever control on
number "5" for thick material and a
lower number for thin material.
Mark the beginning and end
of the buttonhole on fabric with a
basting line or tailor's chalk. Make
one on scrap fabric following di­
rections below to be sure machine
adjustments are correct.
