It's hard to stay neat and tidy if your possessions don't have a home. Your t-shirts may go in a certain drawer, cutlery in the top drawer in the kitchen, your toothbrush in the toothbrush holder, but what about everything else? In order for your home to not be cluttered, things must have their own home. Which means one thing: storage.
Storage may take many forms. From custom built wardrobes and kitchen cabinets (I recently stayed in a house where even the fridge was hidden behind the cabinetry) to boxes large and small, you need to consider a variety of storage options for your home, to meet all your needs. Some smart storage choices you may like to consider are:
Woven boxes to go on shelves and store trinkets and odds and ends. Multiple identical boxes look particularly pleasing on a bookcase. (Byholma Basket, Ikea)
Dividers in your kitchen drawers other than just cutlery trays, especially for your large utensils, to make it easy to find what you're looking for. (Utensil Tray with Grip Base, Howard's Storage World)
Just remember that the more you own, naturally the more storage you need to have. And sometimes rather than getting more storage, that you may not have room for, you should really be getting rid of some of your stuff.
