BUTTONHOLES
To establish the correct length buttonhole required add
)4
inch to the cutting space for bor 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. 28).
First mark the beginning and end of the buttonhole on
the fabric with a basting line or tailor’s chalk. Make one
or two buttonholes on scrap fabric (following directions
below) to be sure the machines adjustments are correct.
(t) Set zigzag stitch width control at 0.
(2) Replace presser foot with special purpose buttonhole
foot. It provides maximum visibility and allows closely
spaced stitches to feed evenly (Fig. 27).
(3) Set stitch length knob 13 (Fig. l) as near 0 as possible
without stopping the feeding action.
(4) Set buttonhole control lever (Fig. 30) at 0 and then to
the first buttonhole setting, between numbers 1 and 3.
This will set the width of the buttonhole sides.
(5) Lower needle carefully into the mark on the fabric
indicating the start of the buttonhole.
Lower presser foot and sew full length of left hand
side of the buttonhole (Fig. 29, Step 1).
