Carusos are the truth!
I used them almost daily when I was neck length. When my hair grew long enough to fit in a pony, I stopped. But they are still here, and I break them out when I need a quick set of curls.
The trick is not to let them sit on the steamer too long. Only for a few seconds, because otherwise they get really wet and will make your hair frizzy.
Also, take them out only when you feel your hair has dried, 'cause that leads to frizzies as well.
I have pics of my Caruso sets in my January or April 2007 albums in fotki.
