My GD recently asked me to show her how to use the zipper foot that came with the sewing machine I recently gave her. (She wants to make zippered wristlets for her girlfriends for Christmas but being a newbie to sewing she'd never tried installing zippers.) Instead I showed her how to install the zipper using a piping foot. I haven't used a zipper foot since the early 80s when my friend Jeanne showed me how much easier it is when you use a piping foot.... just set the piping groove on top of the zipper teeth, slightly adjust needle to correct side of teeth for stitching and sew.
