I'm not usually a monogamous knitter--and strictly speaking, I haven't been entirely monogamous. But I have been largely only working on the Olive Bristow sweater, and it is really coming right along! I'm about 2/3 done with the right front, and the left front and the back are already done. I may block them as I start the sleeves. Then, button bands and finishing, and--voilà!--sweater.
And then I can get started on Christmas knitting...!
