I did this style around the beginning of Summer 2009. I got the idea from Heather and loved it! I have been meaning to do it again but I have such a long 'to try' list, as most of you may already know. lol :)
I start parting down the middle, about half way back, or where ever you want your heart to be, then I just start parting the heart. See the arrows on how to start parting the heart, repeat on the other side. Twist it or braid it up, and of course add barrettes or beads!
