We feel the invitations should be as exciting as the party so we try to be creative...and for our most recent sleepover we came up with this unique invitation..We planned on having pizza so we got from our local Pizza Hut empty (not used) pizza boxes (the "personal pan" size which I think is about 6" square), one box for each invitation. We cut pink paper the size of the box and glued it to the inside top and wrote the party information on it. In the bottom we put a COOKIE PIZZA. We made it out of sugar cookie dough, red icing, and a variety of candy for toppings. We wrapped the cookie in saran wrap, placed in box, sealed it and topped it with a bow. My daughter just loved helping make the "pizza" invitations as well as delivering them. Her friends talked about the invitations for a long time...
