I thought this was a very interesting article about the correlation between knitting and magic(k), specifically the making of knots: Blogickal: Knitting Magick.
She talks about the book The Knitting Goddess, by Deborah Bergman, which I also have. I love the passage that was quoted here:
The invitation to knit usually doesn't arrive when we are feeling like everything in life has achieved a measure of Parisian fullness and balance and needs to get roughed up again. Not always, but more often, it seems to be in one of those ragged, odd moments of life - when we are feeling somehow at odds, in transition, at risk, out of sorts, or just plain awkward - when two needles and a skein of something intriguing manage to present themselves within arm's reach. A voice whispers in our ear. We pick up the rudimentary tools and fiber, put up with the fleeting added challenge of learning yet another new skill, and the next thing we know we are knitting our way through our transition, ordering our life into a new pattern while we also use our hands and needles to learn to pattern yarn. We counter one transition with another, and get through both, and then some.
I haven't been knitting very much lately. It's a very busy time of year, but I somehow need to find the time to sit down and knit a few rows; I think it would probably help to calm and center me.
And maybe try some knot magic.
