Save the Date cards have become standard for most newly engaged couples. They are eager to share their good news with family and friends and they want them to make arrangements to celebrate their big day. These cards can take many forms- magnets, postcards, photo cards, and calendars. Many couples create a website that includes all the information about the ceremony, reception, hotels, special dinners and brunch. Save the Date cards usually include the last line that says a formal invitation will follow.
