So I was taught when you spin your fiber into yarn it is a single. When you take two single yarns and ply them together you get a two ply yarn. There for you can never have a single ply because a ply can never be single. To ply means to twist the two or more singles together. You can have a three or four or even a five ply yarn. I just wanted to clarify that because what was on my wheel for today's post, a yarn single (because I didn't ply it). I washed it and set the twist. I love the colors of this skein so much I think I am going to keep it for myself. (Sorry for the bad lighting, I had to use my flash).
