Round and round it spins, with four photos inside to view! These have to be the most unique graduation announcements that your friends and family will get this year! A circle card holding four photos is built into the middle of this card, and when you spin the edge, your photo changes in the die-cut circle on the front. Make it even more fun by choosing your own colors for the red background, ecru artwork and text. On the back, there's room for your party details and another photo (which doesn't spin). It's super easy and fun to create these unique graduation announcements. 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.
