- one medium to large cardboard box
- one utility or craft knife
- one wooden dowel, at least 5/8 inch in diameter and long enough for your purposes
Try to find a box with flaps or panels with no writing at all on them - it'll make the finished display look much better!
Also, I think it would be adorable to use a branch. That was my original plan, but it rained for a nearly a week before the day of the event, so that would have been sketchy. :P
