Cotton, 5 inches square.
Two pieces of cotton, cut crosswise, from a 5 inch square.
Join the strips in running stitch to each end of the first piece, with warp parallel to warp.
(a) FACED Hem. Turn one of the joined pieces up the full width and make a blind hem. Baste, take up two threads of the cloth, and pass the needle 1/8 inch inside the fold. Draw through and start the next stitch at the end of the last.
(b) Extension Hem. Turn the second piece up half way and hem to the seam.
A bias facing should be used on a curved edge. When sewing on a facing by hand, hold it toward you. A binding is a narrow extension hem.
