I should have followed the instructions and began and ended the bias at the hem. It was really early in the morning, and quite honestly I thought the top neck edge was the hem. Again, Miss A doesn't mind. I doubt anyone will examine the interior of her jacket closely anyway, you should feel privelged to be able to see it. So pretend the serger thread is brown too, okay?
It seems very warm when paired with the jacket. Miss A is one of the "hot bodies" in the family, and I didn't want her to be too warm. I'm glad it is all finished.
