I didn't want to pick up stitches to knit the sleeves in case I'd decide to rip and reknit the front, and that's where I left it. Well, it's funny how a simple solutiona can take more than a year: I'll fold it in half instead. No overlapping, but it looks fine and the opening is big enough - and there will be no ripping or reknitting.
Teaching twined knitting is a great way to spend a Sunday! At one point they all looked so serious concentrating on mastering the technique that I couldn't help joking with them, saying a photo of them right then wouldn't attract many people to my workshops - which made one of the participants say yes, they probably looked like Judge Robert Rosenberg!
