Sizes and measurements for the hat include:
Small~ 18”/45cm, Medium~ 20”/51cm,
Large~ 22”/56cm, XL Large~ 25”/63.5cm.

There is really no super thrilling story about how I came to design this hat. The truth be told… I designed this hat for my husband Jim, his color choices by the way, and shared a photo of the finished hat on Facebook. I soon received quite a few messages asking me for the pattern…Voilà ~
Jim was camera shy so my brother Bill stepped in. Bill is wearing the Adult size hat.

The hat is worked up using the Fibonacci number system ~ Pretty sure you figured that one out from the title. :)

In the pattern I provide the color chart along with the written instructions. I also provide a link to my video tutorial instructing how I knit the increase needed for a couple of the sizes. No worries… This hat knits up very quick and is fun!

Enjoy!
