Wording Samples – The content of your save-the-dates should be short, sweet, and to the point – providing a basic who, what, where and when. There is no standard wording; they may be as formal or as whimsical as you’d like. In any case, make sure to include ”Formal invitation to follow” somewhere on the card.
You may also consider doing customized printing on objects that will grab attention. For example, a pinwheel or a fan.
If you know what your theme or colors are going to be, you can incorporate that into your save the date cards as well. You can also include your engagement picture if you have one. You can have these cards made at a bridal shop or stationery store. You might be able to get a discount if you order the save the date cards when you order your wedding invitations.
Rules & Etiquette – Again, few rules apply. The only information you must include is your names and wedding date, although I suggest including location information as well so wedding guests can begin their travel plans. Aim to send save-the-date cards soon after you secure your date and venue, or about 4-6 months prior to your wedding. Remember, everyone who receives a save-the-date also receives an invitation, so have your guest list finalized prior to sending them. You can, however, always add guests later (there is no rule that says everyone must receive a save-the-date card). Although formal replies are not required, you can get preliminary attendance estimates through word-of-mouth.
Your save-the-date can take any size or form. If you decide on mailing cards out, then your cards can be the size of a postcard, or even smaller. Make sure the size does not cramp the wordings together.
