I've checked back on this mod numerous times over the years but you've never returned to it. Flax providing a source of string is excellent for early gameplay. It's an alternative to dealing with spiders in the early game.

I could also see the mod being expanded on. You could add in cotton and reeds alongside flax, all of which can drop string directly or even a plant fiber item which could be used to craft string as well as other possible things.

At the very least, maybe you could roll this thing into terrestria?
