I'm notorious for not labeling any of my fiber materials. I know I dyed this, but I have no idea what it is. It might have been Shetland roving. Either way, I spun it up and plied it into a 2-ply yarn. The white spots don't look right. Now that I've done some dying of roving, I realize that you either have to leave a lot of the natural color (white) or dye over all of it. If you leave just a little bit, then you get the random white spot that looks out of place.
