Here are some I check frequently:
Fig & Plum - scroll down to see the Norwegian Stockings. Someday I will make Norwegian Stockings.
Grumperina - a master knitter who has never knit a hat. Hats are all I'm good at! Go figure. And author of the Jaywalker sock that is all the rage. Free pattern.
Yarn Harlot - author of this book that I have that is real funny. She has two major strikes against her but I can ignore the strikes because the blog is pretty great. The strikes are 1) she's Canadian and 2) she talks about her cat.
Aside: Lots of knitters talk about their cats. It's usually pretty annoying. There's pictures of shawls and pictures of cats in every entry. If the yarn talk outweighs the cat talk, then I can deal. But if the cat is giving it's opinion on every knitted object, I move on.
see eunny knit! - This blogger has lost me with her in depth discussion of steeks. You can't even find a definition of steek in the dictionary! Nonetheless, if you look at some of her finished objects, they are nothing short of extraordinary.
