Another well received way is to print a mini calendar page with a 3-hole punch so your friends can attach it to their own calendars. Of course, you would have to circle or decorate the day that belongs to you.
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.
Save the date cards can take the form of any message medium, and often do. They sometimes correspond in style to the wedding invitations, or they take the form of refrigerator magnets, brochures, postcards, booklets, or tri-fold letters. The medium is up to you, but the shortness of the message usually lends itself well to magnets or small cards.
If you are on a tight budget, you can either do it yourself, or get predesigned cards. Look out for them online, or go through stationery stores. These work equally well. Be sure to keep your messages short and simple, and you’re on your way to making your own wedding save-the-date cards!
What you should do – Since this will be your first written contact with most of your guests, it’s important that they make a good first impression. Make sure that you spell each guest’s name correctly. If you are unsure about the spelling of someone’s name, look it up or contact someone reliable.
