Tried it on, and the way the sleeves were done is WONKY. So, I ended up unraveling the entire thing.
The new sweater is done in one piece, because the whole seaming thing made no sense whatsoever, and the sleeves will be bottom-up for one repeat before the join. That will, hopefully, work better.
Also, the new one will have a color change each vertical repeat, and is more tightly cast on in the first place.
I think I'll be happier with this.
