Super simple, super fast to knit! You can knit up an entire weeks worth of colors in no time! This is so easy, why not make a few for a friend for her birthday! Uses worsted weight yarn, and knitting needles, US # 15. Sizes are from 36 to 48 inches. We wear these and call these popover tops! Because we pop them over a blouse or shirt for extra warmth on cold days! Good to wear when you go for a walk too.
