4. Buy an Over-the-Door Organizational System
This is not exactly a DIY item. It's a $ 16 door-crossing organizer system. We recommend buying this item, as it gives you a large amount of storage space that can be hung on your closet door. It has both the front and the back. This is perfect for anyone living in an apartment, and you don't have much attic space.
Along with storing under the bed, this is a great way to save everything away so you can continue to store it every year. Even if you don't have a lot of Christmas items, the extra space can be used for other holiday items like birthday paper, and more.
