Knitting pattern Nitis Cashmere hat from "Air"

The Nitiknitti Cashmere Hat is a flexible one-size-fits-all style that, thanks to its stretchy yarn, fits a wide range of heads. It can be worn casually as a beanie or in a classic cuffed style—either way, it's a stylish accessory.

You need 3 balls of Cashmere Air (there will be quite a lot left over from the third ball...perhaps the beginning of a matching twilly).
