Crochet Slouchy Fit Hat and Hairband/ Ear Warmer pattern. There are two sizes included . Small to medium size is 9 inches long by 21 inches around. And Large is 91/2 long by 22 inches around. I have included pictures of almost every row. Made with 1 skein of sport weight yarn, and a g or h hook. The bottom edge of the hat is made with a smaller F hook for both sizes. Written in American Crochet Terminology
To make to bottom band larger, use the same size hook as the top of the hat. Chain 96 sts. Then on row 1 of the skull pattern skip 4 sts in between instead of 3. Complete the hat as written.
