Step one: learn to knit. I sort of knitted a rectangle once by virtue of not knowing how to bind off a stitch or change direction, but that's about it.

Yup! You'd want to watch #1 and #4, then, for the knitting scenes. There's quite a lot of him in #2 as well. Personally, I thought #2 was the best one so far this season, which makes sense because it was an Espenson episode.
