The Moto Vest Pattern is a versatile piece that can be worn over shirts and lightweight jackets or under coats. Flip the collar for a scarf-shawl-like look. Change the gauge or type of yarn . I’ve used T-Shirt yarn for a summer version, light worsted weight yarn for a thinner cold weather version, Habu yarns for an artsy every day wear version and Stash yarns too! Just figure out your gauge on said yarn, how wide or narrow you want your vest, cast on for that width and away you go on your Moto adventure!
