Activity for Elizabeth

I got this idea for a guest book from Martha Stewarts magazine a while back-At each table we are going to have a cute notebook with a question on the cover for guests to answer... Now I just need some ideas as to what questions to ask! Can you think...

Just wondering how far in advance you plan on sending save the date cards? I am getting married September 16 and I would like to send them out soon-Is it too early? Thanks!
