This shell-patterned headband is worked in rounds and has a button fastening.

This headband can be worked in one or two colours of yarn, the pattern indicates when to change colours if you choose to use two.

8ply yarn and 4mm hook are recommended, but you may use any yarn/hook combination that creates the effect you want and that fits around your head.
The fsc chain in the pictured product is about 60cm long; you may either adjust your yarn/hook size to achieve this size, or you may increase the original chain by multiples of 8 and add another shell for each set of 8fsc you add.
