The ribbing of the sleeves is about 6 rows 0f 42 stitches.
This is the sleeve worked up about a quarter of the way.
Here is one finished sleeve. It came out longer than recommended but I am hoping it will still workout. It still looks proportionate to the back of the sweater.
The sleeve looks really nice when it is folded over. It gets much wider than the top, but it is hard to tell from the photo. The sides kept rolling up on me. They will sit much nice once it comes time to block the sweater pieces.
The two sleeves are all finished and ready to go. Now it is time to work on the front of the sweater.
