See Eunny Knit! is by far the best knitting blog I have encountered. Her genius is immediately apparent as she shares her knitting tips and patterns with her readers. If you haven't read this one, you're missing something out of the ordinary...and that's an understatement. How she has time to do all the things she does and blog about them will amaze you.
It sounds like she has a book in the making (no surprise), and knitters will snap it up as fast as it becomes available.
