Very nice slubby yarns, I dyed large skeins of this and am using what I need for my embroidery project, the rest has been broken down into 20 yard skeins and are available in myshop. They have been dyed with natural dyes, cochineal, osage orange (the rayon turned orange for some reason) and natural indigo.
I just loaded a bunch of these beauties to my store: http://www.prairiefibers.etsy.com/ The degummed was is most excellent for needlefelting and for using as doll hair - wild dolls hair!
