Gertie from Gertie’s New Blog for Better Sewing shares a video how-to on Sewing Secrets (the Coats & Clark blog) showing how to add an exposed zipper to the back of a skirt. The construction is a little different than a typical zipper insertion because the seam allowances get turned to the right side of the skirt and hidden underneath the zipper tape. The video is from her appearance on the PBS show, It’s Sew Easy. Go to her video to see how to do it.
