I am too tired to brain today. Here; have an open thread. Ask anything, bring up anything, whatever makes you happy (although I ask that you avoid detailed book spoilers—I have forums for that).

I will brain later, but right now, I have the dumb.

Traditionally/naturally-dyed protein-based fabric uses iron as a mordant. Do you think that having as much as 7% iron content in a fabric would deter fae? Is this an excuse to wear black?

Uh, I mean to get a black color with natural dyes on protein fibers (wool, silk, alpaca, yak down) you need to use an iron mordant. (Other mordants won't quite get you black.)

...yes.

That's a VERY GOOD REASON to wear black.

I also remembered I had this yarn with "10% cool steel," which was a very fine wire of steel spun with the cotton. They make some yarns with real silver too. Handknits that repel faerie magic w00t!
