Fake Food Boxes
Craft Knife or Scissors
Glue Gun/Glue Sticks
Packing Tape (optional)
1.Use your fake food box to determine the width of your cardboard fillers, then cut strips of cardboard at that width, then, cut rectangles from the strip at the same length as the box.
2. Once you have enough rectangles to fill the box, use the glue gun to stick the pieces together.
3. Put the stack of glued cardboard inside the box then put some glue on the end of the cardboard stack and close the box, gluing the end shut. Repeat for the other end.
To further the lasting ability of these boxes, you can laminate the exteriors by wrapping them with a layer of packing tape.
