I am curious about this. I went to my LYS to buy Elsebeth Lavold’s Silky Wool - it was a lot more expensive there, but at least they can wind it into a ball for me.
It got me thinking about yarns that are wound into a ball versus not. I can think of many expensive yarns that aren’t wound into a ball. And, I can think of many that aren’t.
In fact, thinking of Berroco’s yarn, some of them are wound into a ball, and some other yarns aren’t.
What determines whether yarn is wound into a ball? I can imagine in some cases it’s a cost thing, but what about the really expensive ones?
