This hat is worked in the round. The cast on edge is folded inward and joined to the hat body, making it double layered throughout, until the decrease.
The yarn I used is a 2-ply sport weight cashmere blend from Copperwood Farms – a darling cashmere goat farm not far from where I live. I encourage you to find some unique (humanely cultivated) cashmere that makes your cap extra special.

Will fit an average sized teen/adult head.
