How did women spin cotton fiber into yarn?

I've seen this. My grandma is from Peru and taught me how. Basically you use this thing that looks a lot like a tall spinner. First you have to stretch the wool. Then put where it begins on the top where the spinner spins.

When you start spinning you have to make sure your stretching the wool as you go. You could go at your own speed, but I prefer you spin it fast. Then after all that, your done! Its pretty hard, but you'd get used to it after a while. I hope this helps your wonder!
