I am looking for a vest pattern for a rather big 3-year-old boy. He wears a size 5T. I'm just looking for something simple with only knitting and purling (no cables!), and preferably top down. I guess I could even do a sweater if it's top down--I'd really prefer something that knits up in one piece (like the Tiny Tea Leaves Cardi I'm currently making).
Thanks for any help!
