For the cardbox, we plan on have two small luggages stacked on top so it would be three total. We are cutting holes out of the top and middle so that the cards will fall into the second one and so that no one can take them. We're not going to cut holes in the biggest one because we are going to stack the two small luggages inside the big one for easier transportation. I also think we will somehow also use it has our thank you display as the guests are leaving so that people will see the full project. But I think people will get to see everything because the sides will be decorated as well. HTH! Just to let you know it is very very time consuming!
