Your RSVP is your Placeholder for the Reception

We mentioned the RSVP date a lot on these invites, and there is an alternate reason other than the obligatory "Hey, we really need to know, because it affects the table and food count."

In the ongoing spirit of sustainability and conservation, we are limiting our paper usage by using these RSVP cards as your placeholders for seating during the reception.
After the reception, if you want to keep your RSVP/Placeholder card for ever-and-ever because you love it so much, thats perfectly fine. We put a lot of work into them.
Any that remain will be used for kindling during the camp out.
Reduce, Reuse, Recycle. :-)

 So, mail it back, folks!
