There really is no gauge here. You can use any yarn you want and the hook that works best with the yarn. As with most granny blankets, just use as many blocks as you need to make the size blanket you want. Have fun with it, I know I did!
Oh, and here is the reveal post with some nice pictures of the finished blanket.
