how to : Fish Tail Braid like katniss everdeen (hunger games)

1 Divide your hair into two large sections, parting straight down the middle. For a sharper look, you can use a comb to part your hair evenly. If you'd prefer the tousled Katniss Everdeen (The Hunger Games) look, though, simply part it with your hands.  

2. Pull a thin strand of hair from the outside of the left section. Pull it over the top of the left section, and grasp it under the right section. In other words, the strand of hair has gone over the left section and finishes under the right section.

• In general, try to use the same thickness for each strand throughout or your braid will look uneven.
• For a more intricate braid, use skinnier strands. It takes more effort, but it looks gorgeous.
• For a beginner, pulling it tighter helps you to learn the method properly.

3. Repeat Step 2 on the other side. Pull a skinny strand of hair from the outside of the right section, pull it over the right section, then weave it under the left section.

4. Keep alternating sides, weaving over and under, until you reach the bottom of the braid.

5. Tie off the end with a hair bobble or elastic. Add a cute ribbon, barrette or charm to give it some personality if you'd like!

• If you feel that the fishtail is too tight, use your fingers to gently massage into the strands a little to loosen it slightly.
• If your hair is really long, more can be done at this stage, such as tucking the hair into a bun, weaving it around your head or across the front, etc. If you have slightly shorter hair, just fishtail it as far as you want.
