From Stitch 'N Bitch Crochet: The Happy Hooker:



Whether you’re from the city or the country, this hat will set your inner cowgirl free.  You’ll love the sassy, free-spirited mood you acquire the moment you put it on.  And don’t forget that cowboy in your life--he’ll want one, too, when he sees how much fun you’re having wearing yours.  The appealing decorative stitch on the sides and the ropelike trim around the brim will hold the interest of the intermediate hooker and add to your stitch library.  This pattern might be a challenge for a beginner, but, hey, if you’re adventurous and ready to expand your crochet knowledge, it will be a fun and rewarding project.
