It is time to finish our waist facing. The directions will be the same no matter what seam finish you are using.
Start by pinning your facing pieces right sides together with your main skirt pieces matching side seams.
Finish pinning all the way around. You should have a bit overlapping the zipper. Do not cut that off.
Sew using a 5/8 inch seam allowance. Be sure to watch your zipper. If you have any metal pieces at the top do not go over them with your needle. Because those metal pieces can break your needle.
Next you will under stitch the facing to the seam allowance you just created. This will stop the facing from rolling up as much as it could when you are wearing the skirt. Go all the way to the other end doing the under stitching.
The under stitching will not be visible from the outside of the skirt, and will really help you prevent facing mishaps.
Now press the facing down all the way around the waist band.
When you look at your zipper you should see some overlap like mine in the picture above.
Fold the overlap so it is even with the zipper.
Now fold it down so that just the zipper teeth are showing. We will have to hand stitch it down.
I like to hold it the area in my left thumb and fore finger and stitch using my right hand. I use a stitch that I also use to bind quilts. I stitch just through the zipper tape and facing piece, not through the outside skirt panels.
This fabric is so hard to photograph up close! But I pull me needle through the fold in the fabric making it invisible except for a small stitch that will show.
This is what my finished facing looks like. All you can see are my yellow finishing knots up near the zipper head.
Here is the back of your skirt from the outside. Nice work! Now all we will need to do is hem the skirt.
