open up the fabric in the center of the buttonhole.

Corded Buttonholes
When sewing buttonholes in stretch fabrics we recommend
cording the buttonhole to increase the stability and to keep
the buttonhole from stretching out.
Loop a piece of heavy thread or pearl cotton over the
nger att the back of the buttonhole foot. Pull both ends
of the cord forward under the foot and tie off the cord as
shown in the illustration.
Sew buttonhole so that zigzag stitches cover the cord.
When completed, release the cord from foot and cut off
excess cord.
Buttonholes in Hard-to-Sew Fabrics
When sewing buttonholes in hard-to-sew fabrics or along
the edge of multi-layered garments, attach the under-plate
(A) onto the buttonhole foot as illustrated.
Place the fabric between the under-plate and buttonhole
foot.
