A material made by rolling, pressing and hammering combinations of fibres froin wool, hair and fur, which are moistened, then heated. Felt is one of the earliest of materials, made even when woven cloth was little known. Felt caps and garments from the Bronze Age have been found in the Danish and German peat bogs; felt was used extensively by the Greeks for caps and cloaks. The material has proved especially suitable in cold, damp climates, due to its qualities of impermeability. in more recent times felt hats have been made from fur fibres, manipulated and pressed, then subjected to shrinking processes. Especially suitable for this are the pelts of beaver, otter and muskrat.
