What self-sustainable curiosities are worth producing?

[Smoopadoop]

I mean curiosities that you can make without leaving the base, like straw dolls, horrible knots, seer's leaves etc

[NOOBY93]

Straw dolls, chicken bones, seer's tealeaves, seer's bones...
That's off the top of my head.

Cone Cow, Feather Duster, Horrible Knot, Leather Ball, Primitive Doll, Seer's Bones, Seer's Tealeaves, Shewbread, Silken Ribbon, Straw Doll

Most all of these are mediocre at best, but will feed up a bunch of alts over time. If "base" includes a mining area that is protected, you have a few more you can add depending on what ore is available. Note: this doesn't include the "random event" curios you can get like weird beetroot, perfect hole, etc on a farm.

Buy HQ chickens from somone, their quality doesnt degrade. So you can feed them with any ql food and still get HQ bones for seer's bones and hq wishbones as curio.
