Postcards, Magnets, Scallop-Edges, Colored Envelopes, Foil Printing...the options are endless when it comes to Save-the-Date Announcements. These traditionally convey the theme/vibe of your upcoming wedding, and it's great to use the same colors and fonts as the rest of the wedding invitation suite. Save-the-Dates, also known as STDs (yes you can laugh) are usually mailed within 6-8 months of the wedding date, or further out for a destination wedding.
