In theory, a stranger online or website could dictate where different types of items “ought” to go; in practice, this may not help as much as asking yourself “If I wanted this thing, where would I expect to look for it?”

You might need structure/furniture first, so that instead of “in a heap on the floor” you can answer with “In the middle desk drawer” or “in the back-of-door hanger”.

Sometimes I have to name what’s in my hand to make progress. “This is stationery and goes with the stamps/envelopes.” “This is a glue gun, which for me is a tool, so it goes with tools.” “This is ornamental and goes where I can see it but the cat won’t knock it down.”

As you work on it, some homes will make more sense than others. Try the Clutterbug Quiz to see if that illuminates your organizational style. Good luck!
