Any closet - regardless of how big it is, can be full of clutter. Closet organization is about editing, categorizing, labeling and storing items in places that make sense.
Sometimes, it's using the right bins and baskets, while others, it's installing shelving. This way you know what you have and where to find it when you need it.
So even if your closet isn't big, you can make it work better for you.
