What do dark elves make their clothes out of?
 

I mean they live miles underground with like, big greasy subterranian cows as their food source, but they still have like, these personalized fine elven garments (evil ones(secretly chaotic good renegade ones)). What are they using for material? Deep sheep?

Silk. Spider silk.

They are skilled illusionists you know.

They make leather from the skin of their victims when they go on surface raids. Also Kobolds.

Didn't it take something like a million spiders many years to produce a decent sized piece of cloth?

Depends on how big are the spiders.

Lloth helps.

She's kind of a big deal in the spider circles.

Giant spider ranches seem like a bit of a logistical nightmare. I mean, how do you keep the spiders in one place? Or from brutally killing each other, for that matter.

Tricking American tourists into sending their kids on a giant spider fun-ride is an attractive proposition though...

There again Kobolds come in handy.

You can't solve all your problems by throwing kobolds at them!

Edit: Note to self: Construct Kobold Cannon that auto-summons kobolds for every shot.
