I am going the two envelope route for our wedding invitations. I've looked and found several pages that discuss how to address the inner envelope, but my question is; do you think it's terribly inappropriate to leave the inner envelope informal.
For example: Grandma or Mom? Or simply listing everyone in the family by the first names?
Our wedding is not a black tie event and the outer envelopes will be addressed per "the rules", but I just feel that the inner envelopes should be less formal, more inviting so to speak. Thanks for any and all feedback!
