Let's get started on Back Yoke Style #2. After cutting your back yoke pieces you should have 2 main panels (a right and a left) as well as 2 lining panels (a right and a left). We are going to start by taking the right side of the 9" zipper and placing it right sides together with our right main panel along the marked zipper placement line (refer to your pattern piece). The top of the zipper pull should be 1/2" down from the top.
Pin zipper in place. Sew along the edge of the zipper teeth back-stitching at each end. Press the main panel towards the right side. The photo below left shows what it is looks like with the Back Yoke right side up and the photo on the right shows you what the Back yoke looks like from the wrong side.
Repeat the process with the left side of your Back Yoke left piece by placing your zipper and left back yoke piece right sides together along zipper placement line.
Press your yoke to the right side along the same as you did with the right side.
Now we are going to grab our lining and place it on top, right sides together on our main yoke. Pin and sew with a 1/2" seam allowance along the armholes to shoulder stopping 1/2" from the the shoulder back-stitching at each end. Pin and stitch along the neckline starting 1/2" down from the shoulder ending at the zipper, back-stitching at each end with a 1/2" seam allowance. You will stop at the zipper about an 1" from the edge. The photos below show how what it looks like by the zipper:
After sewing both sides you will need to clip/notch your curves making sure not to clip through your stitching:
Turn your back yoke right sides out and press well. Fold your lining center back seam allowance under and press well:
Pin your lining in place and edge-stitch along the zipper catching your lining.
Place your back yoke right sides together with your back bodice along the top edge, pin, and then sew with a 1/2" seam allowance. Finish your raw edges. Press bodice seam allowance towards bodice. Optional: top stitch along the bodice edge.
