How to Compost With Felt

Read the label for fiber content. Although wool is the most common type of felt, manufacturers make felt out of cotton or any animal fur, and some felt contains synthetic materials such as rayon. Synthetic felt does not break down.

Use with greens. Compost piles need to have more carbon than nitrogen, so use more greens than browns.

Use sparingly. Some shearing processes use chemicals to raise the undercoat for easier removal. Some dyes are also undesirable in a compost bin.

Add more water than you usually add. Felt naturally pulls water in, so your compost becomes drier until the felt is saturated. Even if you soak the felt before adding it to the pile, the water requirements are still higher.

Create thin layers to trap heat. A thin layer in your pile keeps the heat where it is most useful instead of letting it escape into the air.
