Bandage
Soak in watered down paint (Choc Brown V872) + White PVA glue.
Dry and cut into shape. Long thin for gun barrel and oval for the sides. Try and cut some strands as they will hand down and look more realistic. I haven't tried but you could stipple other colors onto the dry bandage (green, light brown, khaki or yellow ochre) before cutting into shape.
Coat with diluted PVA glue to harden up the Hessian.
