To be totally honest, I'm not disappointed, but I'm not exactly thrilled about the finished outcome either. There some bits that I wish I could go over and do again, such as the button hole at the back of the collar. It's off centre by about a fingernails length, and it's totally gonna bug me!
I'm also not really thrilled about the state of the buttonholes on the cuff either, and if I'd thought about it more I wish I'd done something different with the inside seams.
However with all of the above said and done, the person who will actually be wearing the shirt doesn't seem to be bothered by any of this.
