1. Rinse each perfume bottle with water, then add a few drops of vinegar mixed with water into the bottles and clean them again. 2. Dry the bottles thoroughly with a hair dryer or similar tools. 3. Arrange and combine the perfume bottles by size or color. This kind of matching layout is highly decorative and can serve as art ornaments, looking extremely elegant. 4. You may put some delicate small flowers inside the bottles to enhance their ornamental value. 5. Store your homemade perfume in empty perfume bottles. Alternatively, buy a large bottle of your favorite perfume and pour it into these smaller used bottles for easier daily use. 6. These empty perfume bottles can be kept in your car for storing appropriately sized screws, nuts and bolts. Remember to stick labels indicating the contents on the outside of each bottle to avoid confusion.
