Yes, I have been writing down the pattern as I go. I don't know how to save it as a PDF. If you're interested, send me an email, and I'll be happy to share what I have written down. Please keep in mind that while I read patterns regularly, I've found that writing patterns is a royal pain in the neck! I make no guarantees that you'll be able to follow my notes!
