Has anyone used the elongated wedding invitations with detachable RSVP cards? I am interested in them mainly because they use less paper (no envelope required unless mailing internationally) but I haven't seen them in person, or heard of anyone using them. I can't decide if using them is a quality idea or not.
Here is an example:
