For those on a budget, I give you my 3 fave tools for organizing the closet without spending much money at all. Each items here can be bought for $10-25 depending on the quality and where you shop. In no specific order, this includes:
1. An over the door shoe rack. These are great!
2. A doubling rod. This give you twice as much space to hang clothes!
3. A closet shelf. Any kind of hanging shelf will do. The $10 cloth shelves that hang from the rod are a classic.
These 3 tools will truly go the distance in giving you lots of space to leverage to clean out the clutter.
