Why shouldn't hats be of interesting character, like folk art? People, even very conservative people, even men will often wear head gear that is less than "normal".  Why not jazz things up with some nice stripes and simple buttons for a one of kind artsy type hat that is sure to suit, well just about any taste.

Another Option For a fun alternate, knit it in the large size, making each stripe a few rows longer than specified in the pattern. (if you wear a large, then add about 10-20 stitches to make it big) Then felt it. Here is a different colorway, felted and blocked (below). The rolled edge becomes a nifty little folded brim. After knitting the hat, I crocheted a simple chain and felted it too. After blocking, sew on the felted separate chain at the top of the hat (shown in orange.)
