Making a Buttonhole on Stretch Fabrics
When sewing buttonholes on stretch fabric, the
buttonhole stitching is sewn over a gimp thread.
1
Using tailor’s chalk, mark the position of the
buttonhole on the fabric, and then attach the
buttonhole foot and set the pattern selection
dial to “F”.
1 Marks on fabric
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
Lower the presser foot and 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.
