Materials: Silkoline 14" x 18"; tape, 2 yards.
Turn and baste a one-fourth-inch fold all the way around the cloth. Crease and baste an inch hem at both ends. With right sides together fold the bag with the two hems together to find the exact bottom of the bag and place pins on the seam to mark this. Instead of sewing up the seams as in making a straight bag, pin the bottom of the bag at the seam to the edge of the hem, and fasten very securely. Then overhand the edges of the sides together in the two folds. Put in two lines of running stitches for the two tape casings; run in the two tapes, 1 yard each, bringing them out at opposite sides for the double draw strings.
