CAUTION
■
Making a buttonhole on stretch fabrics
When sewing buttonholes on stretch fabric, the
buttonhole stitching is sewn over a gimp thread.
1
Follow steps
1
to
6
from “Making a
buttonhole” on page 38.
2
Hook the gimp thread onto the back end
of the buttonhole foot, bring the two gimp
thread ends to the front of the foot, insert
them into the grooves, and then
temporarily tie them there.
3
Set the stitch width to match the diameter
of the gimp thread.
4
Start sewing.
5
Once sewing is completed, gently pull the
gimp thread to remove any slack, and
then trim off the excess.
Adjusting buttonholes
If the stitching on the two sides of the buttonhole is not
the same, you can make the following adjustments.
1
Set the stitch length dial between “F” and
“1.5” and sew the buttonhole on a scrap
piece of fabric to observe how the
material is fed.
2
If the right side of the buttonhole is too
open or tight, adjust the feeding of the
material with the stitch length dial.
1
Right side
2
Shorter
3
Longer
3
After obtaining a satisfactory feed on the
right side, stitch the buttonhole and
observe the feeding.
4
If the left side is too open or tight
compared with the right side, adjust the
buttonhole fine-adjustment screw as
described in the following paragraphs.

2

Buttonhole appearance
●
When opening the buttonhole with the
seam ripper, do not place your hands in
the cutting path, otherwise injuries may
result if the seam ripper slips. Do not use
the seam ripper in any other way than
how it is intended.
