4-Step Buttonhole stitch
Buttonholes can be adapted to the size of the button.
For stretch fabric or thin fabric, it is recommended to use a stabilizer for a better
buttonhole sewing. Slightly reduce upper thread tension to produce better results.

Using the buttonhole foot.
Note
Please use the same fabric of the project
and do a sewing test in advance.
Measure diameter and thickness of button
and add 3mm for bartacks to obtain correct
buttonhole length; mark buttonhole size on
fabric.
Place fabric under the foot, so that marking
on the buttonhole foot aligns with starting
marking on fabric. Lower the foot, so that the
buttonhole center line marked on the fabric
aligns with the center of the buttonhole foot.

Follow the 4-step sequence changing from
one step to another with the pattern selector
dial. When moving from step to step through
the buttonhole process, be sure that the
needle is raised before turning the pattern
selector dial to the next step. Take care not to
sew too many stitches in steps 2 and 4.
Cut the center of the buttonhole being careful
not to cut any stitches on either side. Use a
pin as a stopper at the bar tack so you do not
cut too much.
Note
When cutting the buttonhole with the seam
ripper, do not place your hands in the
cutting direction, otherwise injuries may
result.
