I'm thinking of starting a knit wig collection, this one is so much fun. I've had this pattern for knitting an Elvis wig, complete with monstrous side-burns, for years now. And just this week I stumbled across a newish pattern at BleuArts for a knit Princess Leia wig, cinnamon bun muffs 'n all. I also saw this great Marie Antoinette Wig crocheted by Jen this month for the September hat-themed Whiplash, but no pattern (yet?).
Now I'm thinking, "I wonder what other wig wonders live in knitting land?" So a-googling I go, and what do I find, but a Cowgirl Wig from Lion Brand Yarns (sorry, but their spies make you register to view free patterns, and this one isn't a knitting pattern, but a cut-and-paste effort, but cute anyhow). I found a reference to a book containing a pattern for a Barrister's Wig on TheJonBlog; the book, Knitting 19th Century Sources by Jules and Kaethe Kliot, is available from Schoolhouse Press and others for around $25. But that was all my short attention span allowed me to find. Feel free to waste more time and find me others.
