• One-Step Buttonhole Control Dial
This dial (Fig. 43j is used for automatic,
one step buttonholes. The length may be
automatically set by selecting a number
or point on the dial between 1 and 5.
Normally, Number 1 produces a button­
hole of about Vi inch in length on stiff
cotton, while Number 5 results in a V/i
inch
buttonhole. Size will vary on
different types of material due to
stretching of the fabric. Once the number
or position has been selected, the button­
hole
size is produced automatically.
Each buttonhole can be made the same
size without any measurement on the
fabric. For normal sewing this dial ts set
at OFF, Further details are explained on
Page 31.

• Stitch Density Control
This control is mainly used for fine tuning
the stitch density of the right side of the
buttonhole and the shape of decorative
reverse stitch patterns. A clockwise turn
of the knob increases the openness of the
right side of the buttonhole.
Conversely, a counter clockwise turn
makes the right side of the buttonhole
closer together and makes the reverse
stitch portions of decorative reverse stitch
patterns longer. Reverse stretch stitch
patterns may be a altered as to closeness
or openness of the stitch by turning the
dial counter clockwise for a more open
pattern and clockwise for a closer stitch
pattern. However, most sewing will be
done in the neutral position of the stitch
density control. (Fig, 44)
