And yeah, I've seen urine used for various purposes, but not as a dye mordant... Not for the squeamish!

20 Natural Dye Plants You Can Forage and Grow in Your Garden

By Catherine Winter

Excerpt: "Would you prefer to go a super-natural route, since you’re using plant-based dyes? If you’re aiming to be as self-sufficient as possible, there are also all-organic mordant options as well.

Natural Mordants:

- Sumac: Simmer fresh sumac twigs for about an hour, strain out the twiggy bits, and reduce the liquid by half
- Urine: human urine is ideal for mordanting, but you’ll need to age it. Collect it in a jar and allow it to age for several days. [🤢 ]
- Salt: You can use standard table salt as a mordant, but Kosher salt can yield some of the strongest color-fastness. [I've used that]
- Vinegar [That too]
- Wood ash lye

"You’ve probably noticed that some of these are alkaline, and some are acidic. Alkaline mordants tend to work best with plant-based fibers like cotton, linen, and #hemp. In contrast, acidic mordants like vinegar are better with animal fibers like #wool, #alpaca, and #angora.

"Note that if you use an acidic mordant and your colors still run, you can set the color by dipping the fabric in a 50/50 vinegar/water solution. In contrast, if you’ve used an alkaline mordant like lye or baking soda [another one I've used], an acidic solution will strip the color rather than setting it." [Been there, done that!]
