A pair of semi-soiled rags.
From rags to riches, or from riches to rags? The former is a bit unclear, but the latter is certainly true. Most fabric and cloth is destined to have a lavish life, either used as clothing, covering, or elaborate decoration. The less lucky ones are at least used to a degree by their owners, either as a rug to sit on, or for cleaning up spilled liquids and mud. When fabric is so heavily soiled, torn, and ripped apart, to the point it is no longer recognizable, it goes straight to the dump, waiting for an ingenious environmentalist or a homeless person to reuse it.
Found in most landfills.
