The Unchained Scarf was inspired by my Unchained Shawl; it is essentially a rectangular version of the shawl. Made with Mango Moon Twist, it is lightweight and great for a spring or summer scarf. The pattern includes directions for how to make this scarf and length and width you would like. Obviously, changing the size will change the amount of yarn you will need.
