WIP Sweater

So the sneak peak I posted a while back showed some lovely blue yarn, though it is a bit more teal than it looks in the photo. The project for that skein of yarn along with a few others is a sweater! Because why not?

Still not quite the right color and from a few days ago.

So far I've finished the yoke and am about 3 inches past where the sleeves and body split and I can't even begin to list everything I've learn while working on this.  Mostly being that I should trust the math and not second guess myself.
