I had yarn to ply today, and I thought it would be fast, as it was only a single ball. So I started plying and plied, and plied, and plied, while I read Ravelry and did other things on the computer. I swear the ball on the pic above is practically the same size as it was when I started, even though the spindle is almost totally full. I was scratching my head and trying to understand it, and then the explanation came to me.
Happy Half-Nekkid Thursday.
