Creative people, please help!

I have found my way to the personalized tshirts at the DS online and want to purchase them for the children of friends who are making their first visit with us in July. I like the princess art that's available there, although I'm also looking at zazzle.com. Anyway, I want to personalize the tshirts, maybe with their names (it's OK with their Mom) and something about first visit maybe, or possibly the date. I just don't know. The first names of the girls are Sydney and Ava.

Any ideas? Please help! I'm not feeling terribly creative today.

THANKS!
