WIYM: recycled cardboard swap

We decorate the cardboard and send it like a postcard?

@creativecitrine u find like a cereal box and cut it down and the back will be blank u write on back of it like a pc and put address on the right side. the cardboard side is left alone so the recipient can see the cut out cardboard. I use beer boxes, cereal boxes, moon pie boxes cool cardboard and cut em down . I have gotten diet coke and coffee ones. its really fun to see different cardboard. hope this helps . if u want to see an example send me ur email in private message and I can send u a pic
