How, if possible can an invitation be sent as late as 12 days before the wedding in order to assuage hurt feelings for not receiving an invitation when others did?

Double post.

If they know others receive it and they did not they will be hurt anyway.

Its not kosher, but just send it. Make it a point to thank them personally for coming.

I think that if you truly want to assuage hurt feelings, then you need to do more than send the invitation. You need to call and explain why they were originally not invited and why they now are. BE HONEST - ex. "Due to limited space in the hall, we had to cut people from our list that we really wanted to invite. However, now that some people are not coming, we are thrilled that we are able to include you." OR "Planning the wedding has been so hectic. We had every intention of inviting you, but somehow your name was left off the list. I am so embarrassed, but it was a mistake."

My husband and I went through the same thing. When it was one of my husband's friends I just apologized profusely and said that I mailed it to the wrong address and it got sent back. Or when we had last minute spaces to fill we called them personally and said that we hadn't received their RSVP yet. When they said they hadn't received an invite, we told them we would mail them another. Problem solved... I know its shady but better than hurt feelings.

Well, this actually happened to me and my husband because we had a box of invites in the back of his car and a couple of them fell out and were under his seat. My friends parents and one of his aunts wonderd where their invites were and we found them cleaning out his car. Not that lying is a good idea, but if you meant to invite them and they got overlooked... do what you got to do. Planning a wedding is HECTIC. People should be a little more understanding in
