Decide on a color for the pantry, and paint the walls inside it. Size does not really matter for this step, as you can paint a pantry of any size, from the smallest cubelike indentation in the wall to a large walk-in repository.
Line the shelves with shelf liners. These come in a plethora of colors and designs. You can find shelf liners at home improvement stores, grocery stores and discount department stores.
Change the shelving in the pantry to fit your needs. For instance, if you have items you want to store that hang down, such as aprons, you can alter the shelving to leave a free space and insert hooks in the wall. Alternatively, adjust the shelves to fit large mixing bowls and small items like spices and oils.
Consider the items you use frequently vs. the items you use infrequently. Place those you rarely use on upper shelves. These might include holiday baking sheets and utensils.
Place similar items together on the shelves. For instance, place breakfast cereals, trail mix bars, pancake mix, syrup and the like on one shelf together. Stack all soups, sauces and pastas on another shelf.
Set the larger and taller items toward the back of the shelf if the shelving is deep rather than long. You will still be able to see these items while utilizing the space in front of the items with small products.
Leave the bottom shelf open for bowls, food processors and mixers. Some of these items are larger and cumbersome, and having them on a lower shelf makes it easier to move them from the pantry to your countertop.
