twin baby pattern suggestions sought

I recently found out a co-worker and his wife are expecting
identical twin girls in June. Thanks to new 3-D ultrasounds,
earlier this week, everyone in the office saw their sweet
little faces. It's amazing how much better this new technology
is than what was available even a few years ago!

Anyone have any suggestions for gift knitting for the two?

I'd suggest something not overly complicated or ridiculously
time consuming and not booties. Other than those two
guidelines, I'm open.

I look forward to your ideas!
