Kelly, bear in mind that I don't blow dry every day... in fact it's more like once a week! Since I work from home I try to let it air dry as much as possible, and then use either a flat iron or my trusty Kevin Murphy rollers (or nothing at all...I'm quite lazy).

Anupa - great post idea! I posted a flat iron curling tutorial here: http://beautyeditor.ca/2009/11/23/get-the-look-diane-kruger-hollywood-awards-gala-beverly-hills/
But I should probably do a more comprehensive how-to post. Added to the editorial calendar!
PS - let me know how you do with Zai!!!
