What does felted mean?
Felted describes material—most often wool—that has been transformed into felt, a dense, non-woven fabric created by subjecting fibers to moisture, heat, and pressure until they mat together permanently. Unlike woven or knitted textiles, felt relies not on interlocking threads but on the natural tendency of animal fibers to entangle when agitated. The word functions both as an adjective, describing finished objects such as felted hats, slippers, and bags, and as the past participle of the verb "to felt," the process itself. In modern usage it is especially common among knitters and fiber artists, for whom controlled felting is a valued technique, though it also appears whenever a wool garment has shrunk irreversibly in a hot wash. Durable, warm, and water-resistant, felted goods have been made for millennia across many cultures, making this word a small window into one of humanity's oldest textile technologies.

Etymology of felted
"Felted" derives from "felt," which traces back through Middle English and Old English "felt" to Proto-Germanic origins, with cognates such as Dutch "vilt" and German "Filz." The underlying idea—matting fibers together—is ancient, and felt-making predates woven cloth in many regions. A notable relative is English "filter," borrowed via Medieval Latin "filtrum," which originally denoted a piece of felt used for straining liquid, showing how central felted fabric once was to everyday craft.
