This is especially money saving if you have young children who like to draw. Often, when something is printed it is only printed on one side and the other side remains blank; if you need paper for something that is not "important" then you can use the reverse non-marked side of the paper. The cost of paper continues to increase and saving money this way may seem like a small amount, but it adds up quickly. Even using the reverse of lined paper for quick notes or other information, can save money. If you need to, draw a quick "X" over the side that is no longer needed.
