gimp thread to remove any slack, and trim

off any excess.

■Odd Shaped Buttons/Buttons that do not Fit into the Button Holder Plate
Use the markings on the presser foot scale to set the
size of the buttonhole. One mark on the presser foot
scale equals 5 mm (approx. 3/16 inch).
Add the button diameter and thickness together, and
then set the plate at the calculated value.

Memo
For keyhole buttonholes, use the eyelet punch
to make a hole in the rounded end of the but-
tonhole. Then insert a pin along the inside of
one of the bar tacks, insert a seam ripper into
the hole made with the eyelet punch, and cut
towards the pin.

Set the width of the satin stitches to the width
of the gimp thread, and set the buttonhole
width to be 2-3 times the width of the gimp
thread.

Memo
For example, for a button with a diameter of
15 mm (approx. 9/16 inch) and a thickness of
10 mm (approx. 3/8 inch), the scale should be
set at 25 mm (approx. 1 inch).
