90 degrees counterclockwise and sew
straight stitches to the end of the front bar
tack of the buttonhole.
Remove the material from the machine.

We recommend that you put pins across
both ends of the buttonhole to prevent the
stitches from being cut.
Cut an opening in the middle of the

buttonhole with the seam ripper tool. Be
careful not to cut through any stitches.
CAUTION
●
When using the seam ripper to open the
buttonhole, do not put your hand or
finger in the path of the ripper. The seam
ripper may slip and you may be injured.
