I managed to spin quite a bit of white wool.  The I wound it into a center pull ball, actually I used to strands to wind a ply ball on my ball winder.  This is the first time I have played with a ply ball.  I put a rolled up piece of paper in the center of the ball so that it didn’t collapse into itself, and plied from the outside ends.

I used a bottom whorl drop spindle and just went to town.

This is my spindle when I was finished, the singles were wheel spun so there was quite a bit to them.  I love how my unwashed skein turned out:

Over 120 yards of 2 ply yarn.  I really liked how the center pull ball worked for plying.  I might just hand wind a tight ball next time, since it will be a silk merino blend, instead of using the ball winder.  Trying to get a tight ball so that the singles didn’t crimp, yet loose enough so that my ball winder didn’t make that awful grinding noise.

The main advantage that I can see from winding a center pull ball is immediate feedback on what the yarns will look like together.  My ply ball would be from the Gemvember box by Paradise fibers and seeing how the separate colors would work together would be a big advantage.

Keep experimenting, there is always something new to learn.

Happy Crafting!
