The space close to the ceiling is prime for storage. It’s out of your way, and out of your line of sight — perfect for things you want to keep but don’t use very often.
We add a top shelf in almost every closet.
In the kitchen, we store bulky items on top of the kitchen cabinets. (The space wasn’t being used for anything else.)
The apartment-beige paint above the cabinets looked rather dismal, so we covered it with a roll of matte gift wrap from Paper Source to add a shot of cheerful color.
