We had a list of about 20 people we wanted to invite to the wedding if we had enough declines from the main list; now that we've had a fair few no's back, I'd like to start inviting a few more - but how exactly do you go about this? I don't want to come across as saying "you weren't good enough for an initial invite, but now we've got some room, you can come along"! I can't just send out another round of invitations because all the inserts we had printed and everything on the website has the RSVP date of March 31st!
How have you gone about it?
