Ok, so I've read that it's impolite to have your registry info anywhere on the invite, although I always see it on invitations I've received in the past.
Anyway, this is what my invite is going to have on the bottom of the direction cards: "For more information on accomodations and the couples' registries, please visit
www.ourknotwebsite..." Suffice?
Thanks!
