Weddingbee boards

Hi ladies,

I fell in love with this idea from Marth Stewart that Miss Rainbow posted the other day: http://www.marthastewartweddings.com/goodthings/conversation-starter-guestbook. Though rather than have a special guestbook table I was hoping to put some cards on every table so guests could write at their leisure, as they thought of things, without any pressure, etc. But I'm at a complete loss for display ideas. The tables are small and will be crowded with plates, centerpiece, favors, etc so it can't take up too much room. Any ideas from you creative geniuses out there? The best I've got is clips like these: http://www.sophiesfavors.com/tabledecorations_heartplacecardholders.jpg and I'm not loving it.

Thanks!
