Making thread, dyeing thread is a pain. No reason not to, but if we came across flax, I'd collect it to make more anyway.

[ He's not spider, he can't magic up clothwork, so it's the good old fashioned way for him. ]

I would treat the leather underneath the fur...[ He pulls it apart a bit where he's working. ] A lot more to soften it, but it takes a lot of work to get it really soft. I've softened it to a reasonable degree, and adding the material to make it extra soft.

Then again, soft pelts would be a novelty. You just get used to it.
