In Europe, the delicate underfur generally known as "beaver wool" was identified to be ideal for felting and was designed into beaver hats and trimming for clothes.[128][129] Later on, the coypu took about as a less expensive source of fur for felting and was farmed extensively in the united states and Europe; even so, fashions adjusted, new elements became out there and this region on the animal fur industry declined.
