A household refrigerator can quickly become chaotic with overcrowded shelves and mismatched containers. To maximize fridge space, use chopsticks.

Simply put two chopsticks on top of a covered bowl of leftovers, then stack another container on top. The chopsticks serve as a stable base to hold another bowl or plate on top.

You can also stack large, deep plates and casserole dishes, as long as the chopsticks span from one end of the container to the other.
