Wool
Wool is an animal fiber produced from spinning the hair of sheep. As a protein-based fiber, wool that is burned exudes the smell of burning hair. Wool flags generally feel coarse and the weave of wool fabric is generally looser than cotton or linen, and certainly looser than silk. Wool is chosen for flags because of its excellent ability to withstand water. Since it is a product of natural animal hair, it doesn't rot as readily as vegetable fibers like cotton or linen. Wool over 200 years old can still be vibrant and supple. Moths do tend to feed on wool, and many holes in wool flags are due to mothing, especially with flags that are stored for years in attics, barns, garages and basements.
