Once again, when I pulled the center strand from my yarn ball, I caught too much and had a little wad of yarn. Previously I have spent considerable time untangling errant threads when trying to ply in this situation, but this time I carefully wrapped the excess yarn into a butterfly on my fingers, and held the small ball of yarn in my palm. There were still some tricky spots, but it went much smoother this way, until I got back to having even pull from the inside and outside of my ball. Wrapping yarn nostepinne style is my favorite way to make a center-pull ball of yarn, and making a two-ply yarn from a single ball is my favorite for when I am walking and spinning. I can take the ball of yarn off my spindle, snag the inside end, and start plying immediately, without having to transfer the yarn first. (And the balls of yarn with their slanted wrap are pleasant to look at.)
