The hat begins with alternate cable cast-on and a ribbed brim. This goes into an all-over cable and lace pattern before rapid decreasing at the crown. There are options for a beanie or slouchy-style hat in the largest size, with or without a pompom. If you make the slouchy-style hat in the largest size, and you want a pompom, you will probably need three balls of yarn. The pompom shown used 12g of yarn.
