Question: For those of you that sent out invitations for fun (meaning to sports teams, celebrities, etc), did you include a letter in there saying why you are inviting them? If so, what stuff did you include? I know a few knotties did this and I think I am as well... but I don't really know what to write. Complaint: I hate that I have to spend money on RSVP envelope stamps for people that I know are either not coming or will just call/email to RSVP. I know it's proper etiquette but it still sucks.
