I think I want to set my RSVP date earlier than we are supposed to because I'm sure I'm going to have to chase people and I want to get my final numbers early on... so if I said my invites out 4 months in advance with an RSVP date 2 months in advance is that good or no? So I have approx. 7 months until I think I want to send them out... when should I order them?
