Every bride and groom knows they need to pick out wedding invitations and mail them in ample time to ensure a good RSVP and turnout on the big day. The truth is there is more to the process than meets the eye. Of course, invitations should include the basic who, what, when, where and why type answers. But, what else should go into their creation? The answer to that question can be a whole lot. Wedding invitations can serve as valuable tools to tell guests about several different things relevant to the ceremony, reception and even gift-giving suggestions. While this information won't necessarily all go on the main invitation itself, you should consider extra cards or inclusions if you want the festivities to be a bit different. For those planning a standard wedding and reception, wedding invitations should go out at least a month in advance. Also, they should include such things as th e bride and groom's names, the location of the ceremony and reception, the date, time and who to RSVP to. Pre-stamped envelopes are a nice touch, too, for the RSVPs. In addition, the invitations might also include dinner order cards and other standard touches. It is acceptable to include special cards with the invitations that list gift registries and preferences. It can, however, seem rude to include them as part of the main invitation.
