Well, yes. But the tow-sack is longer and full of cotton bolls, so it can carry much more volume than the very heavy (high density) potato sacks - which yo have to pick up and haul around.
Yes ma’am MamaB, it takes a lot of cotton to weigh that much. I never once managed that much! LOL!
Robert, I’ve never even seen a bag of potatoes, I’ve never even tried to grow them. Although I do remember printed sacks of flour. (I’m old!)
