I am making my daughters program with a picture of them as babies & their engagement picture on the cover. Anyone have ideas for a saying to go with this.
I don't think you need any text at all -- the pictures say it all, without being cutesy.
Just out of curiosity -- you said, "a picture of them as babies" -- does that mean one picture of both of them; i.e., that they have known each other all their lives? Wow, that would be so cool to have a picture like that. I would be tempted to leave off the newer picture, in fact!
No, it is an individual picture of each of them. They've only know each other 4 years.
