Here's the thing with fading fawn fiber: if you send it to a mill or card it up without forethought, all those various shades of fawn will blend together = one color. I have plenty of alpaca blankets that I could spin into yarn that are one solid color. They are beautiful and all, but I love, I LOVE, the various shades in a yarn. And with fading fawn, you can do that without using any dye. All natural.

That yarn can create products with variegated colors. Here is a hat made out of Tehya's fading fawn fiber that is for sale on our farm's Oak Haven Alpaca's ETSY shop:
