Save the Dates are becoming more and more standard now a days. People are so busy and the months fly by. It is a good idea to let your guest know when you are planning to have your special occasion, especially if you plan it for a holiday weekend or you never know when people plan their vacations. Not everyone goes away in the summer or holiday time anymore.
Here is an example of a really unique save the date. This is a gatefold design. The bride and groom's child/baby pictures are on the folds and then in the inside is one of their engagement pictures. A very cute idea!
