I made a February baby sweater for their newborn daughter, I used a wool/cotton blend yarn in a lilac/green color. It turned out beautifully. I really like the pattern and the yarn combo and will use it again!
They also have a son, so of course big brother needs stuff, so he got a pack-pack (pattern from LTK of course). I filled it with crayons, paper and stickers, everything a 4.5 year old needs!
I hear the presents were a hit! :)
