I call it the lace braided ponytail and this is what it looks like when you're finished.
You will need:
A doll with medium to long hair
A hair brush
Start by taking a section of hair from the front of your dolls head.
Then begin a basic braid.
Add another piece from the front of her head and braid a little more.
Keep adding sections from the front of her head.......
... until you get to right above her ear.
Braid all the way down and secure with a hair tie.
Lastly, pull the rest of her hair to the side of her head and put it into a ponytail. Then you can take the hair tie securing the braid out and you're done!
