Here is a fun quick project just in time for the holidays. I saw a similar hat and decided to make it up myself. Help yourself to the pattern, click here to download the PDF file.
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.)
