Stuff it underneath the bed: When you lived at home, your bed was probably a “catch-all” with everything from dirty clothes to un-clean dishes. Now that valuable space can be turned into a storage haven. Organization is the key, so place your lesser-used items into plastic bins. Try to keep similar items together, and mark the lid with a sharpie, so you don’t have to open every bin to find that much-needed item.
Use every inch of your closet: Purchase a double-hang closet organizer like this one. All you do is hang a rod from your existing one, and you’ve just doubled your wardrobe space. Don’t think of your closet as just for clothes. Purchase plastic stackable drawers in which you can cram your miscellaneous items.
