For example, just look at the photo above. On the particular day in question (which was back in 1988, I believe), I was wearing one of my favorite dresses -- this navy minidress with sash belt (that I'm pretty sure was supposed to tie in the back, but I wanted to be different and tie it in the front). I obviously had to pair it with a yarn ribbon headband in navy to match.
I really never even saw other people wearing yarn as hair ribbons, so I don't know where the idea came from. But it's one that stuck around for quite some time!
And, yes, my hair was rather big. But I sure am loving my blunt bangs!
