Spin the wheel to read all about the party details on these unique graduation announcements! A wheel peeks out from the edge of the two-sided card, and friends and family spin the wheel to read your message in the curved, cut-out window on the front! Use the text on the wheel to invite them to your open house, with all the details, and choose any color for the background. Your photo and class year are also featured on the front of these graduation announcements. The back features a chalkboard background, and has room for your name and high school as well as a special message. (You can leave the message area blank if you wish.) A mix of vintage and modern, these graduation announcements are sure to be remembered. 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.
