How to make a crochet hat the right size - I have been using this same method lately. Its hard to follow a pattern exactly when you are constantly using different yarn. For an adult female, the hat should fit if you crochet a circle until it measures 5 1/4 FLAT (stop your increases at that point). For a mans hat, stop you increases when your circle measures about 6 1/4 FLAT.
