The block layout of these graduation announcements holds a patchwork of four different photos, solid colors, pretty damask patterns and editable text! Choose from over 70 different colors for the pink and gray background colors and patterns to create a theme for your party. The photo areas are small enough to work well with Instagram and Facebook-size photos. On the back of these graduation announcements, all of your party details are highlighted against a solid color background of your choice. These two-sided graduation announcements are sure to please! Square envelopes are included and require additional postage to mail. You also have the option to choose rectangular envelopes instead, which do not require extra postage and have a pocket inside to hold square-shaped cards without shifting.
