I had a lot of fabric left after sewing some pillow covers for a friend, and she let me keep the extra. A good bit of it became this Boppy cover for another friend’s baby shower.
I have a new favorite way of sewing zippers, which I found on some website I neglected to bookmark. You first baste the opening closed, then pin and sew the zipper in, then remove the basting. That way, there’s no distortion, and the two sides meet perfectly in the center of the zipper.
