What are you most proud of? The pattern had a zipper in the back. I decided to place the zipper in the side seam. It was the first time I have installed a side zipper. What advice would you give someone starting this project? Take the Mastering Zipper Techniques class, and buy a zipper foot for invisible zippers if your machine does not have one - they really make a difference. I have installed several invisible zippers before, but after watching Sunni, I was inspired to try the side seam on this dress.
