Here’s the beginning of the sleeve for Arrows. I’d completely forgotten about doing two round things on circs so I could indeed do two at once but I think that’s a bit too challenging for me on my very first Fair Isle sweater so I’ll be content to do one. I’ve also not got more than one ball of anything and I know I don’t want to knit from both ends of the ball as my knitting gets really twisty and that would make me crazy. I’ll keep it in mind for future sweaters where it might work though, glad you all mentioned it! The sleeves will progress fairly slowly as I do really need to pay attention when I’m knitting them to be sure I do my increases every 3rd row. Once I get past that point it’ll be mindless again. This first sleeve now is about 1/3 of the way through the increase section and then it’ll be straight knitting from there.
