The original photo probably wasn't the best to identify the problem with the hoodie; but if you guessed that the neck shaping was done incorrectly, you were right. This is a better photo of the front of the hoodie. Looks like a turtleneck, doesn't it?
The instructions were crystal clear that shaping was to begin at the center front, and I did it exactly backwards so that the shaping is at the shoulders instead of the neck. I can't tell you what thought process went through my head; but, hey, at least I was consistent--I knitted both front sections the same wrong way.
