WHAT IS FELT?
Felt is a pressed, matted fabric formed by the interlocking of certain unspun fibres, most notably wool. No spinning, weaving, or knitting is involved. Rather, through a combination of heat, moisture, and pressure, each individual fibre become completely entangled with the other fibres around it. The tangled mass forms a natural, self-tightening, felted mat. Looked at under a microscope, felt appears as just such a tangle of intertwined fibres, with irregular open areas."
Felt retains a percentage of natural lanolin from the sheep. This combined with the density of the felt will repel water and make it a product that is windproof and showerproof.
