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.
Although wedding save-the-date cards are not part of the etiquette for a wedding, it is wise to make use of them. It allows your guests to be able to set aside time for your wedding in advance. Generally, people would like to know about your wedding as soon as they can, especially if they are keen to attend. Also, if travel arrangements need to be made, then it is best to be informed early.
You want your save-the-date to look unique, personalized and funky; so that it can attract your guests’ attention and make them want to attend your wedding. Save-the-date cards for weddings should ideally reflect the couple’s personality, and the wedding tone.
To save yourself time with licking the envelopes, you might consider stickers. You can purchase round stickers with your last initial or a rose or heart. These can be found at the stationery store or where you are purchasing your invitations. Another option is to purchase glue sticks to seal the envelopes.
