I have a very old pattern, early 50's, late 40's, which I've used before which uses stocking st and reverse stocking stitch to create layers, and has a very flat top. So I thought I would use that to create this hat.
I love it. It's just what I wanted and is suitably fun and suitably practical. It's now for sale on Etsy, as is the very large skein of the slubby stuff.
