Make your neckline bias binding/drawstring casing from your fashion material, using the guide on the pattern sheet. Pin binding around the bodice neckline, beginning and ending at the center front and folding under the center front edges as shown in the instructions.
Stitch, taking care not to catch the bodice lining pieces as you go.
Trim seam allowance down to 1/4" and clip curves.
Fold under the raw edge of the binding and fold the binding to the inside of the neckline to create the drawstring casing.
Press neatly and pin in place.
Stitch, making small running stitches all the way around the neckline and making sure outside stitches are tiny, even and neat.
