Yarn selection: This hat calls for worsted weight yarn (gauge 20 sts to 4″/ 10 cm; typical needle size US 7/ 4.5 mm). You only need about 75 yards per color with the two-color stripe as designed, but the pattern could be easily modified to include more colors or be worked as a solid. This pattern is great for making a hat with school or team colors!
