Wow. People like my sweater. I'm... surprised and gratified. Yes I will definitely write up a pattern, at some point. I'm going over the page proofs for my husband's next book, and we're on a deadline that is made shorter by the fact that the proofs have to be mailed to and from the U.S. So that's taking most of my time right now.
And... well, you've seen my other patterns, they're a bit haphazard, a bit stream-of-consciousness. I don't really know how to write a pattern well enough to sell it - if people pay for something, they expect it to be really good, and I am no Marnie MacLean (seriously, the woman is a genius; how does she DO that!?). I'd have to figure out how to knit the sweater in 10 sizes, and ack.
So those are the major obstacles, and I am thinking a lot about how to get around the second one. The first one, I know what to do: get back to work!
