RUH - Real Ungulate Hair; had to change the name since I used elk for the wing and body. Took the basic Carnage framework and draped it with said ungulate hair. Notional tying sequence; body's a bit chunky, a few less tail fibers next time. Tied here as a Fall Drake; change color/size to suit your needs.
