The pattern includes instructions for two sizes - adult and kids - but is easily customized to fit any size, which is described in the pattern.

The amount of yarn needed depends on type of yarn and size made. Two balls (330 meters) of sport weight yarn should be enough for making the adult size.

The shape of this hat is the traditional Swedish Santa’s hat (’tomteluva’), which is also worn by santa’s helpers (’tomtenissar’) according to Swedish Christmas traditions.
