Tip 4: Closet Doublers. It is a simple thing that I bought a while ago that has enhanced my closet space and given me my sanity back. I used mine in my children's room so they could reach their dresses. But, you can use this in the coat closet to create more space...either for adult items or kid items. And since some people use their coat closet floor for other items, closet doublers are a great alternative to using baskets on the floor.
