The shoulders are seamed! I matched up the ribbing and everything front to back. Though, now I am looking at the instructions for the sleeves and (gasp!) there's math involved. Someone definitely should have warned me about the math. I would have been happy to knit him a vest.
I've got the second sleeve on the needles with a lot to go, but the girls have a playdate in the morning and I plan on taking advantage of the time to knit while I chat. Must finish sweater before company begins to arrive!
Any hints on sewing the sleeves would be greatly appreciated.
