I spoke with a bride today who was surprised by her reaction to "will not attend" response cards. She had expected to feel disappointed when people weren't able to accept, but she didn't think she'd also feel stung and even a little insulted.
Here's what interested me: The simple checked "no" box seemed cold to her. No one wrote down "sorry to miss it" or "wish I could be there."
That's partly why you've seen more and more of our sample invitations containing blank reply cards. Guests have to write something in their own handwriting!
Have you gotten "regrets" yet from your invitations? How are you reacting?
