Number Charcuterie Board out of Cardboard

For my son's 14th birthday, I decided to put together a number charcuterie board. 

I used a large cardboard box that I had from buying items online. I drew the base of the one and four on the cardboard. Then I cut those out. I then measured the sides of the numbers and cut 3 inch sides to be placed around the numbers. I hot glued the sides into place. I then covered the inside of the cardboard with pieces of press n seal. I then arranged my bowls and food around the numbers.
