I'm posting Fiona & Keith's save the date cards. These were beautifully letterpressed using two colours and a thick Strathmore off white cardstock. Fiona sent her save the dates out 8 months prior to her wedding date. We basically started working on concept and design 12 months before. I feel save the date cards should be a simpler version of your invitation design. Perhaps not as formal with a fun twist. Design elements should be carefully chosen so your guests only see a hint of your upcoming invitation design. Save the date cards also give you the perfect opportunity to expose your guests to your wedding website, hotel information or other important tips you may want to communicate very early on especially if you have many out of town guests.
