Your photo stands out against the chalkboard background on these graduation announcements with a (surprise!) spinning wheel of photos hidden inside. Friends and family spin the wheel where it peeks out along the right edge of the card, and the photo changes through the die-cut circle on the front to one of four different photos you can put on the wheel. On the back, there's room for your party details. It's super easy and fun to create these unique graduation announcements. And don't forget, you can order risk free with our happiness guarantee. 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.
