Homespun Handknit: Caps, Socks, Mittens and Gloves which is, alas, now out of print. You can probably find it at your local library or there may be a used copy available on Ebay. There's a new version of this book out but it unfortunately does not have the same patterns.
You can see more information here on Ravelry. I like the variations in color for this hat and I'll probably make it again.
I enjoyed knitting this hat late at night, listening to the rain falling on the roof.
