How long should the brim of a hat be?
If the hat pattern you are using provides a finished measurement for the brim rather than the size it fits, a good general rule to follow is that the brim of a hat will usually have about 2″/5cm of negative ease. That means the brim will measure about 2″/5cm less than your head circumference.
How do you decrease evenly in knitting?
