Baby sweater is done

I finished the baby sweater and will give it away today. Other than buttonholes I think it came out ok. I am not sure how to make the holes so that they wont appear so big. I guess I have to practice making them more often or figure out how to make it with the sewing machine. The link to the pattern is in the previous post. I think the pattern is not well written. When you connect sleeves to the body it helps if you just use an extra needle for few rounds.
