I've just been watching Dirty Harry and a couple of the girls have their hair tied up in bunches with what looks like mega-super-thick wool. I suddenly thought a) I remember loads of girls doing that when I was a kid in the 70s, and b) I don't remember seeing that since I was a kid in the 70s!

Does anybody still use that wool stuff? Does that wool stuff even exist any more? Does anybody under the age of 40 even know what I mean?
