You might know all the ins and outs of sending wedding invitations, but save-the-date etiquette is sometimes less clear. Save-the-date invitations are sent to your guests six to eight months before your wedding date so that they can mark it on their calendars. It's okay to send your guests a wedding save-the-date by email, but don't forget that this wedding card is really the first introduction your guests will have to your wedding, so a lot of couples are imagining unique ways to incorporate their theme. Creative save-the-date wedding cards are available in a huge variety of styles, from DIY to professionally designed keepsakes. Having a destination wedding? Design your save-the-date invitations as messages in a bottle or to look like vintage tropical postcards. For a rustic country wedding, consider branding your wedding save-the-date on a wooden coaster. You don't need to include as much information on your save-the-date wedding cards as you do on the actual wedding invitation, so be sure to check out our tips for save-the-date wording tips. Not sure who receives a save-the-date? Read up on save-the-date etiquette articles to make sure no one gets left out. One thing to keep in mind about these wedding cards is that they can be a lot more low-key than your formal invitations.
