Would Amy’s method for winding a center pull ball be sufficient to use 2 strands from one ball like you can with a pull skein or no? I know I’ll have the yarn vomit at the beginning, but besides that, will it then flow pretty well pretty much?
Thanks! 
I’ve done a center pull ball with two strands and it worked fine. Mostly I just use two center pull balls when I need two strands since they unwind so nicely. When they become really floppy after most of the innards are used up, I’ll re-wind what’s left of the two into one center pull. Does that make any sense?
