Creating a center-pull ball of yarn using a "nostepinne" takes practice, just like everything else with drop-spindle spinning. Many things can serve as a nostepinne, even cardboard bathroom tissue rolls. This yarn was wound on a vintage weaving spool I happened to have. It makes a great nostepinne, but I still need much practice. If interested and that's a new word for some of you, google it. There's a short You Tube video that I like best.
