The hat is called the Whirling Hat and I thought it was rather ingenious and cute. Although, I am not the cutest model!!
I found the pattern HERE. The original hat was made form an old wool sweater. I stopped in the resale shop and found a wool sweater that had conveniently for me, been lightly felted. I have a feeling that someone accidentally threw the sweater in the wash and of course it came out too small. Their bad fortune, my good fortune :) Thankfully they had the wherewithal to give it to the resale shop.
The hat can be made from fleece or any stretch knit fabric. She even gives instructions for lining the hat if you would like.
The pattern looks a little like a flickering flame. The shape of the pattern makes the hat automatically fit the shape of the head.
You will cut 6 pieces for the hat. I used the lower edge of the sweater for my cut pieces. This worked out great as I had a nice ribbed edge all the way around the bottom of the hat.
Here's one that you might like to use.
One last thing. If you try the hat on and it's just a little large, you can easily take it up by just stitching in along the opening end of the hat and blending the stitches back in towards the crown of the hat.
