Make things efficient, convenient and accessible by storing items where they belong. Stack containers neatly. Categorize your stuff and keep things in each category together. When your storage space is overflowing it's time to start tossing stuff. Buy aesthetically pleasing, good quality shelves, cabinets, dressers and desks if they will be displayed throughout your home or business.
Closed cabinets are neater.
They don't show your clutter. Buy the tallest, widest bookshelves, cabinets and dressers that will fit your space. Room to grow is the key here. Have a stepladder handy to reach the tallest shelves and spaces. Have only one junk drawer and every once in a while go through it.
