After completing my Debbie Bliss Taking a Break sweater, I had one hank of discontinued Rowan Magpie Aran wool left over. You could use any Aran weight wool. I decided to use a cable from the sweater and make a headband to co-ordinate. The cable is a simple four row pattern repeat. Keep knitting for approximately 22-24” / 56-61cm or when the headband feels comfortable for you. Cast-off in pattern. To finish, you can simply join the band in the normal manner or add a twist  To learn how to make the twist, I followed instruction by Mirella Moments. Here is a link to her tutorial. https://pin.it/7qDShoW. https://www.sewatelierm.com/my-headband-inspired-by-debbie-bliss-with-free-knitting-pattern/
