My local knitting guild held a one hour workshop to learn about inserting zippers in knitted garments. We brought to class two small swatches and learned how to hand sew a zipper perfectly. After the class, I sewed up the sides, embellished the front and back with small seed beads and now have a cute cel phone pouch hanging from a keychain on my tote bag. The best part about using this is that strangers want to talk about knitting! FYI, zippers are inserted in knitting the same way as sewing with an optional knitted or crocheted edging finish.
