I have a teacher who is pregnant and would REALLY like to make her something for her and her (soon to be) son. She will probably have her baby around March if that gives you an idea on how big she will be in December. She is normally an average to petite sized woman.
Maternity patterns?
Have you seen the Napoli from Berrocco? I posted about it here. There might be other patterns on that thread, I don’t remember.
The Summer 06 issue of Interweave Knits has a very cute maternity sweater, Mommy Snug.
You’d have to order the issue, but there’s also some really cute kids things in there.
There is a new book out.
Expectant Little Knits
Or you could make her a nice shawl or something that she can use when she’s nursing the baby (if she is). It’s nice to cover up a bit if you are.
