I created this neck warmer for a quick Christmas gift. It takes about 2 hours to knit up. There are no button holes. Just sew the buttons through both layers of fabric. Other pin-type closures (kilt pins, shawl pins, even jewelry) would look great, too. For men, use leather, horn or bone buttons. If your button has a shank, use a back button so the shank doesn’t pop through. This is a great scarf alternative and can easily be stuffed into a coat pocket.
