In Europe, the comfortable underfur called "beaver wool" was located to be ideal for felting and was built into beaver hats and trimming for clothes.[128][129] Afterwards, the coypu took around as a less expensive supply of fur for felting and was farmed thoroughly in the united states and Europe; having said that, fashions altered, new components grew to become obtainable and this area with the animal fur market declined.
