This Bucket hat pattern is a made to measure pattern which takes your own yarn weight/ hook size into account as well as your own tension (you are not required to meet a different gauge to change sizes for this hat, there are instructions to adjust the size of your granny squares with all of these factors kept in mind)

This pattern can also be used to make a hat with different granny squares as long as they are of similar size. The possibilities are only limited by your creativity!
