Stitch the side seam. Stitch the seam from the bottom up. At a point 5 inches from the top, turn and stitch half way across the seam. Turn both edges of the seam toward the front section and press.
Trim the seams. Start at the bottom of the wide seam and trim it to ⅝ inch wide up to the placket. Do not trim above this point.
Finish the placket
1. Baste and stitch a ½-inch hem on the back edge of the placket.
2. Fold the front edge of the placket even with seam line. Press. Now fold again to make a complete hem. Baste.
Pin placket together. Stitch from the top to the bottom of the placket, turn and stitch across the end of first stitching. Pull threads through and tie ends. This is a strong, easy-to-make placket.
