Because it has been a pain to manage animal hair separate from wool so to avoid having my farmers workshops full of (nearly) useless thread, and worse yet, to avoid having dyeries dye the wrong thread.

Which is to say, I'd really like a mod that either just have only wool-bearing animals drop any sort of hair/wool when butchered, or, alternatively, make so that I can weave any and all sort of animal hair thread into cloth.
