Clip the curvy corners (as we did when we attached piping to the armhole), and then turn the collar inside out.
Sew the collars to the neckline once you have positioned them well.
The last step is to sew a bias tape to hide the raw inner edge of the collar. Cut 1.5-inch wide bias strip from the same fabric you used for the collars. The length of the bias strip can be a few inches more than the neck. Fold the bias strip in half, place it above the collar on the right side of the dress, and pin it around the neckline. See the images below.
Press the folds using your thumb. Remove the pins, fold down the bias strip, and pin it around the neckline.
To avoid the bias strip showing up on the right side, you need to pull it down and pin on the top as well as on the bottom of the strip. I didn't pin on the top before I hemmed it. Therefore you could see the strip peeping out a little (in the image second from last).
Hem the bias strip.
Your Peter Pan collar is ready now.
Tomorrow we will see how to sew a pocket to this dress.
