New Project - Baby Sweater

I found a pattern that I understand, so I'm giving it a shot. So far, I've been confused by how exactly the arm holes are made, but got through it. And, I had to remove a few rows of the "shell" stitching (on the bottom - the part with the big gaps) when I finally realized what the pattern was saying.

This sweater is for a friend of mine who is due to have a baby girl in June. The pictures don't show just how much pink, purple, and other colors are mixed throughout the blue, but trust me, it is definitely a "girl" yarn. I can't wait to post the finished product!
