The pattern said to lightly block it, so I opted for the steam technique. Here is a picture of one sleeve blocked vs. unblocked.
Here are both pieces blocked.
I had to pick up stitches along the edge and add "neck" stitches in between.
After picking up stitches, I started knitting stripes with the Dirty Panther colorway.
This is the back of the sweater. I'm happy with my progress today. I am in stockinette city, so this should be moving along pretty fast, even though the yarn is in fingering weight.
