This is the Rikke hat pattern, and I love it. It comes out enormous and squishy and comfy, and it’s the world’s easiest hat pattern. It also doesn’t poof out on the sides like a lot of the slouchy hats I’ve tried knitting. It’s made of madelinetosh tosh dk, which I would use exclusively for the rest of my life if I could afford it. Here’s my ravelry page for it if you want to give it some love, which you should.
