This is made from a box from the U-haul store. The original idea was to take any square shaped box and cover it with colored paper, but this box happened to be red so it made the job easier. Using clear shipping tape, page protectors are taped onto every side. That way whatever you are working on can be changed in and out. There's nothing inside the box so it's lightweight and transports back and forth to Church really easily. Hope this helps Torri!
