That can't be right, because I made a scarf and hat out of two hanks, and they're both patterns I make quite a lot of. I know the scarf take 180 yards along, and there was enough yarn left to make all but the last 5 rows of the cloche (which I finished with a matching solid color.) Just from using it to make these items, I'd say there has to be at least 100 yards to a hank.
