9. Use a seam ripper to cut open the center of the buttonhole,
being careful not to cut into the ends of the buttonhole. It is
helpful to place a pin at the end of the buttonhole to serve
as a stopper while cutting.
NOTE: For sewing buttonholes on projects such as hard-to-
sew fabrics or along the edge of multi-layered garments, install
the underplate. Place the fabric between the underplate and
Buttonhole Foot.
