Is there a way to wind the ball so that you can knit from both ends of the skein without it hopping away from you (as would happen if you made a center-pull and just knit from the "inside" yarn and the "outside" yarn at the same time)?
Hold both ends and wind a center ball as normal.
It's easier to knit from both ends of a center-pull ball that is wound on a ball winder because the ball then has a flat top & bottom, IMHO.
I've knit from both ends of a hand-wound center pull ball, and a regular old skein (are they wound by machine? hmmm) Anyhoo...I've never had any issues with the skein/ball jumping around. I'd envisioned it being kinda cumbersomebut it wasn't at all.
I'm going to have to do this real soon, like today, on a clog.
Me too! That's exactly why I asked.....
I just tried it out last week on a skein from the store which I did not wind and it worked just fine.
