I found this idea over at Then She Made, and HAD to try it out for myself! It was really easy to make, and used items that I already had around the house.
Grab an empty soda box, paper (I only had colored printer paper, but I think a nice wrapping paper would be better, you can get some at the Dollar Tree and should make a few of these in matching prints), and tape! You will also need scissors, but that was pretty much a given. You will want to cut a hole in the back, on top, that is a little larger than a can of soup.
I started out by folding the paper around the edges of the open end of the soda box and taping it all in place.
Then I did the same to the top, and finished it off by wrapping the sides and adding a label to the front. These can be stacked a couple high and will keep your pantry neat and organized.
