In the home stretch
I'm about two inches or so from the front collar shaping and am very much enjoying the rapid decreasing at this point. The rows seemed soooo long after joining all the pieces together.
I may be reporting an FO within the week. I have a fair bit of "will it fit" anxiety, but will try to chill out. I ended up with five buttonholes rather than four, more due to my poor planning than anything else. They are at least evenly spaced.
