Piping is a cord covered with material cut on the bias, and is used to strengthen and finish the edge of a garment.
No. 8 needle, No. 60 thread, a small cord eleven and a half inches long, a bias strip of cotton cloth twelve inches long and one inch wide and a piece of cotton cloth eleven and a half inches long, four inches wide, hemmed at the ends and one side.
1. Place the cord on the wrong side of the bias strip, one-fourth of an inch from the lengthwise edge, and one-fourth of an inch from the end.
2. Fold the end of the bias strip, and then folding the edge over, baste close to the cord.
3. Holding the cord downwards, place the wrong side of the strip to the right side of the piece of cloth, with the raw edge of the fold even with the raw edge of the cloth.
4. Sew the piping to the edge, with a running and a backstitch, keeping close to the cord.
5. Turn to the wrong side, and hem the opposite edge down.
