Since they’re giant spiders and therefore giant webs, it’s actually not that bad an idea…
It’s a fairly involved process, basically there are several steps before you get to “thread”, then it would proceed as usual.
The only problem is it’d be fairly pointless until we have a system that tracks quality of components, right now we’d either have clothes made from spider silk that’s identical to other clothes, or duplicate every. single. piece. of. clothing. and. recipe to be spidersilk specific D:
I guess we could have a hybrid approach, where we plug spidersilk into most recipes, and have a few special recipes that are spidersilk-specific, that wouldn’t be too bad.
I would be totally happy with the webspinner mutation being one you can turn on and off, and maybe balance it by it making you hungry when you use it.
