Braids for '08

I love love love the trend that's popping up everywhere for summer 07/08 for braiding the front of the hair, then leaving the rest loose or in a messy ponytail. It's right up my alley, embracing the relaxed, folky style that I love. But I'm struggling with it for myself. I'm yet to master braiding the front without getting a big part just behind the braid.. and with dark hair the part is extra obvious. Can anyone give me some tips on the easiest way to achieve this style?? It's set to become my summer staple if I can get it working...
