Horsehair 

Arthur, my rescued horse who kindly provides me with horsehair when I need it. Arthur was found abandoned in a field when he was about 3 years old and taken in by the World Horse Welfare. He was adopted by me when he was about 4 and has been happily living with us ever since. He is now about 20 years old and is very tolerant of the occasional haircut.
