How many balls are in a skein?
I'm working on a felted bag, and the instructions say I need three balls of one color.
HOWEVER.. Aren't most yarns sold in "skeins"? Which I think are the oblong products. Instead of the round "balls".
On another package of yarn I have, it says that in the skein it has 6 balls.
So... are balls measured? I'm so confused!
