Foley artists need a wide assortment of props to stock the Foley stage. They also need a prop room in which to store them. If they can manage some kind of storage near the stage for regularly used items, the props used less often can be stored farther away. Most major Foley stages have both kinds of storage. Smaller stages and multi-use studios modify the storage for props. Foley artists develop a sense for seeing everything in the world as a potential Foley prop and want a place to store these items. Any kind of organization system works, as long as they can find what they need when they need it. Foley artists have three main categories of prop sounds for any film, episodic show, or game. Robert Rutledge is credited by some in the Hollywood community with the innovation of the single cloth pass.
