I'm done! And it all came together smoothly, much to my relief. Not that I expected trouble but when you are sewing for someone else, you kind of hold your breath.
Even when sewing the midriff lining down, on the inside, I tried to keep the stitches tiny and invisible.
I put the zipper in exactly the way the instructions said and it went well too. In this photo, the zipper allowances are still basted together.
This is what the zipper looks like on the inside, with the tops of the tape tucked in and the top edges of the bodice folded under. I took some tiny hand stitches to secure the edges even more and then added a hook and eye at the top.
And here is the dress, on my judy. It doesn't zip up the back because my niece is narrower than I am. And it will look even cuter on her, as she is cute too! I am going to request a copy of a photo of the dress in action but that won't be until June. And now for the Vogue dress!
