I bought this book for my wife. She's a novice knitter but has made some really cool things from it quite quickly. I would recommend it to anyone who wants to make this sort of thing but isn't sure how.
(Not sure if I'm allowed to post links to books on here but can't see anything against it in the sidebar. Sorry if I FU.)

That's the Amazon page for the book I got the pattern from.
