This is Squiggle Hat. There is absolutely nothing special about this 8X80 knit hat other than the i-cord that squiggles down from the crown and ends with a button.
I am still enamored by the top of hats. Lots of opportunity for creative embellishment.
And that's all I have to say about it.
PS - Frog Tree Ewetopia yarn. You should buy some. It is great.
