I have obtained my most expensive fiber to date. Camaj Fiber Arts had a sale on Guanaco fiber, which is harvested from wild animals in South America. Because they are not domesticated animals, the fiber is harder to obtain, hence the cost.

I will not be blending this fiber, but spinning it pure and making swatches for my fiber books.

And yes, vicuña is on my wish list, along with qiviut.
