I made this pattern for a few years ago. At first I knitted a headband to myself, then to my daughter, then to friends and family... and then I sold a number of them too.
The design is casual and you can use it from fall to spring, no matter what clothes you are wearing. It also useable under a helmet if you bike.
The headband fits a headsize from small to XL.
Knit it in a few hours.
