I know some people mentioned the trick of using an invisible ink pen on the back of the RSVP cards in case a guest forgets to write their names. Well I was at the Dollar Tree earlier today and found one in the toys section! For $1, I figured I try it and it and it works. I'm glad I found it before I spent $10 on one from Amazon. Just thought I'd mention it. Here's a pic.
