Start the zipper halves at the same distance from the top raw edge. There should be no twists in the zipper. Repeat the stitching process for this second side stitching from top to bottom of the zipper and adjusting the foot and needle for stitching of the opposite side.
In this photo you can see that I am using a tucking foot to
apply the first side of the zipper. The zipper teeth are right up in the groove of the foot and the needle adjusted to come down very close to the teeth.
Right sides together, ready to stitch side two
Here you see the invisible zipper foot that fits my machine. I've don't the stitching in red so you can see, well when it is visible, where the stitching is.
Starting at the top....
Working from the top of the zipper stitch down as far as you can go. The zipper pull will prevent you from going all the way to the end.

Check the zipper placement by pulling it closed. The two sides should be the same. Check things on the right side. Here you see the zipper is closed and the seam is not stitched below the zipper.
|From the right side|
Sometimes there is a small gap at the bottom of an invisible zipper which can only be closed by hand. You may wish to stitch the bottom tails of the zipper tape to the seam allowance to give the zipper more stability.

That's it for tonight. Still more to come......
