SINGER 8019 - Manual (Page 42)

buttonholes
You have a choice between two methods of
making bar-tack buttonholes; using the built-
in four-step system, or manually controlling
the selectors.
On pages 41 and 43 you will find detailed
instructions for using the two methods; but you will
find the following information basic to both.
1.
Always make a test buttonhole on a
sample of your fabric. Be sure to duplicate
the thickness of the garment. Include inter­
facing if appropriate.
2. Use No. 50 or finer mercerized cotton
thread or embroidery thread, and reduce
needle-thread tension to slightly less than
normal.
3. Use a size 11 needle for embroidery thread
and a size 14 needle for mercerized cotton
thread.
Buttonhole Position
Accurate guidelines are essential to keep but­
tonholes A at a uniform distance from the edge
of the garment, evenly spaced, and on the
grain of the material.
Mark the centre line B of the garment. This
guideline can be made by hand basting. The
space from the centre line to the finishededge
of the garment C must be from 1.9cm (3/4") to
the full diameter of the button. D With this
spacing, the button will not extend beyond the
edge when the garment is buttoned. Make
sure the centre line marking follows a
lengthwise fabric thread.
Marking the Garment
e Mark a position guideline with hand basting
for each buttonhole.
e Horizontal buttonholes 1 are placed to
extend 4mm (1/8") beyond the centre line of
the garment E, as illustrated, so that buttons
will be in the centre of the figure when the
garment is fastened. Horizontal buttonhole
guidelines should follow a crosswise fabric
thread and should be longer than the
finished length of buttonhole. Mark ends of
buttonhole vertically.
• Vertical buttonholes 2 are placed on centre
line of garment E, as illustrated. Mark ends
of buttonhole horizontally across the centre
line basting and use the centre line marking
as the buttonhole guide when stitching.
Spaces between buttonholes should be equal.
When a line of buttonholes crosses the waist­
line, be sure that one buttonhole will fall ex­
actly on the waistline. Then measure the
other buttonhole markings from that point.
