Partway up the yoke and the pattern is coming along nicely.

Finished with a shorter collar the the sewn bind off. Just the grafting at the underarms and wash & block to go.

Over 100 degrees here at the moment so much too hot to take photos wearing the sweater. Even the idea is making me break out.
