I was so careful with my wedding invites, but totally spaced it on my rehearsal dinner invites. It wasn't because of the weight, but because they were square. I put 30 in the mail on Tuesday and no one has gotten them yet. I got one back that Wednesday, which is how I figured it out. I called the post office and they said they would either be returned, sent to the recipient with postage due or go through just fine. Do you think if by Tuesday, no one has received one I should just make new ones? The wedding is a mont away, so would like to get to them in the next week or so. What do you think?
