So I worked some more on the vest yesterday and I got the back done. Or at least I thought I had.

Looking at the pattern again, I realized that I messed up. The front and back are supposed to be made joined at the shoulder, and only the sides need to be flipped over. Instead I made this one solid piece for the back. So I have to start all over. Well, I guess I technically don't, but it will be easier to do that. Such is life!
