So I was reading Wedding Bee and one of the brides had the best idea ever! to avoid the issues that come up when a person forgets to put there name on an RSVP card or it is unreadable writing she bought a black light pen and put the persons initials so she will know who it is from, I am totally doing that and thought I would share!
i think it will work well. so far so good with people putting their names and it being legible, but its a just in case thing. and no extra expense with the black light!
I did the same as pamnandy.
