Turkish spindle yarn wrapping finally clicked with me. I’ve been following the “over two, under one” guidance for wrapping the turtle of yarn around the arms of the spindle, and I finally saw the pattern begin to emerge and was then able to follow along.

The key, for me, was on which side of the previous wrap of yarn to put the new wrap of yarn. To start a new layer, the “two over” strand goes right next to the shaft, and the “one under” goes on the outside of the yarn under the spindle arm. As I wrap, the yarn goes outside the wraps next to the shaft, but inside the wrap under the arm. Ah ha. This method is slow, but satisfying; a good meditative practice.
Even though my previous attempts at a geometrically balanced turtle were not successful, they still worked beautifully as center-pull balls of yarn. In the picture above I was making a two-ply yarn from the center and outside strand of one turtle. So whether or not the ball of yarn is messy, it still does its job.
