I know I'm a little late with actually following the trend, but now my layers have grown long enough for me to braid away. I'm having a lot of fun trying new styles. The cool thing about braids is that they can hide bad hair days or allow you to go a day or two without shampooing and still look clean. Here are just a few pictures:

Fishtail braid. So easy to do, but time consuming if you want a lot of loops I guess you'd say.
