Green Tweed and the Mysteries of Knitting

I started a new pair of socks with my handspun wool/mohair from MDS&W. I'm using the Harris Tweed stitch pattern and its looking strangely like horizontal pleats. For some reason this sock reminds me of an accordian. When I was working on the sock, I got to thinking about strange things that knitting does and how I don't know why it does these things. When I knit my first top down sock, I couldn't fathom how it was possible to get a shaped heel when I was reading the directions. I still think its a magical moment when you turn a right angle in a tube that's knitted around and around. Lace? Lace can stay straight if the decreases are right next to the YO's but if you move them a bit away, you get curves or points in your lace - all from knitting back and forth. I don't really want to know exactly how knitting does these things. Its like finding out how a magician does a trick - you never really look at the trick in the same way. I guess its enough to know that these things can happen and I just enjoy it when they do.
