This pattern includes 3 sizes for both brim and head size. The cover features the extra wide brim, but the crowd favorite is the medium brim - perfect for gardening, sun protection, and activity. Choose between the classic small brim, the medium brim, or the extra wide brim. The size options for the head go from small to large. We found the small fits children well, the medium and large fit most adults. The hat can be made out of almost any substrate from quilting cotton, canvas, corduroy, Shannon Cuddle, to Sew HungryHippie soft vinyl! Beginner friendly. Full sized pattern pieces included!
