What kind of closets? Office, bedroom, hallway, bathroom, laundry??
Bernie, if you click on "explore projects" then "organize" then type "closets" in the search box and hit enter, you will see a good number of ways to organize closets. I have chosen one for you, but there are many that might help in different ways: https://www.hometalk.com/1760155/my-7-total-closet-makeover
Here's a link with some ideas to get you started, Bernie:
Declutter first. If you don't wear it, get rid of it.
Bernie...My daughter and her husband moved to a new house about 3 years ago. When then moved in they hung all them clothes in the closet with the opening of the hanger toward the front. As they wore each item they hung with hanger facing the back. They moved in early December and each item that hung toward the front was removed and taken to a ministry such as Goodwill or Coordinated Charities. They were very pleased knowing if they had not worn in 3 years it was no longer necessary to keep. Hope this helps a little.
