I think it would be interesting addition to this game.
Another source of cloth. As wiki says its pretty bad cloth IRL, so maybe this shouldn't be able to raise real q, or just half it in recipes.
Mostly it should be semi-automatic production and a new color - grey probably.
Made it like a compost bin system with only herbs(bark and leaves too), would be nice compare with a cattail to produce mass cloth early game.
Instead of monstrous fields or mouflon-clover abuse.
