I'm knitting a sheep from sheep's wool. Benedictine sheep wool to be precise. The pattern is both simple and complex. Simple in that it uses only one stitch - the knit, and few variations on it at that (a mid-row turn and an increase). Complex in that nearly every row is unique. Follow the pattern slavishly and you end up with what appears to be a sheep skin growing off your needles. It never fails to amaze me, or those watching me. I realized it is like DNA, you read off a linear code to produce a 3-D object. Even though I understand the principles behind both processes, the mystery of creation remains.
