This crochet hat is made all in single crochet using a tweed yarn with a brown stripe. The pattern is crocheted to look like a knit. Finished size is 10" long by 21" around unstretched. It stretches to fit most heads. I used my stash of yarn for this hat. It is very forgiving on size if your gauge is close. You can try a smaller or larger hook to attain this.
