Curling hair with a flat iron!?

Yesterday I was at the mall and a woman at a booth was selling flat irons. I already have a great one so i was not interested but then she showed me how to curl with it. Can someone refresh my memory on how to do it?Curling hair with a flat iron!?
It's better done with a thin flat iron, like the ones that are just a inch or so. You straighten you're hair as usual than at the bottom instead of letting go, leave it and start wrapping your hair with the flat iron. Leave for about 10 seconds or more than uncurl.Curling hair with a flat iron!?
It's kind of like a curling iron, you just twist your hair around it, or to curl the ends out instead of taking the iron straight down your hair, lift it out and up a little, to add a little curl at the end.
all you have to do is use it like a regular curling iron. just flip up or down the ends and wrap the hair around the flat iron
get a good grip at the root and just barely bend for a slight bend - or twist all the way around as you slide the iron down for a tight or springy curl.
