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 creative and want to save money, you can create your own save the date cards using either card stock paper or regular paper. This will save you money since you will be printing them yourself. You can be real creative when you design these. You can include a picture on the paper and include any other personal details you would like.
You should send save-the-date cards to all of your intended guests when either of these circumstances fit your situation. Even friends and family members who you already know will attend should be sent a card.
There are many types of save-the-date. Although a save-the-date is traditionally a card, it can also take the form of magnets, bookmarks, or wedding stationery. Any type of save-the-date can be a meaningful keepsake of your wedding day. They also serve the purpose of giving your guests the first indication of what your wedding will be like and what to expect at the wedding reception.
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.
