I have made some progress on my vest. The current total length is about 12 inches. I am going to add an extra inch to the length, then proceed to split the front and back, and do the armhole shaping. So, I am almost back to the point where I originally frogged it. Here are some pictures comparing it to the sweater that fits really well. It is about 1 inch wider, but I can live with that. It leaves room for a button-down shirt to be worn below the vest.
Taking control of your knitting is very liberating!!!! I am smiling for real now.
