This is an easy pattern for an aviator hat with 6 sizes, so siblings can have matching hats!
Instructions are given for both knitting flat and in the round. Just choose whichever is your preferred method.
The earflaps are button fastening under the chin to keep little heads from wriggling out of it, and tiny toddler hands from pulling it off after two seconds, but if you are knitting for an older child and want the earflaps to hang freely just make two of the left earflap and don’t add a button.

If you are a relatively new knitter there are plenty of pictures to guide you.

This pattern is now also available in Spanish
