Fold with the warp through the center, and cut an opening on this fold five inches in length. Then follow the directions for making the gusset. Sew the two sections together with the French fell. Hem the sides with a quarter-inch hem.

Exercise No. 35—Buttonholes.

Materials: Blue Percale 9" woof by 4" warp; scraps of calico for practice pieces; white thread No. 40 and No. 80; needles No. 7 and No. 8.

Remember the old adage Practice Makes Perfect.

See description of the Buttonhole, [page 63].

Note: Scraps and odd pieces of calico can be used for the practice work on buttonholes. As the buttonhole requires a great deal of practice it is well to keep these pieces in the sewing box and work at it at odd times during the progress of the years' work. Encourage the girls, too, to practice on the buttonhole for home work. In this way they will gradually acquire the skill which only comes with practice. Fold the cloth, wrong side out, with the woof and through the center, and baste the edges together. Begin with the blind buttonhole.

The buttonhole model is intended to show how much skill has been acquired. Fold the percale through the center, with the woof, and baste the edges together. Make the buttonholes three-fourths of an inch long and one inch apart.

Fold with the warp through the center and cut an opening on this fold five inches in length. Then follow the directions for the Nightgown Opening. Hem the side of the narrower part with a quarter-inch hem.
