Simple Twist

This one is really easy!

I sectioned off quite a bit of hair on top of her head, and inserted an elastic.

Next, I split the "tail" of that section into two parts and made a twist. (Twist both strands to the left and then wrap them around each other to the right.)

Then I secured the end of the twist into a second elastic farther back on her head.
Add a cute clip (or not!) and you're done!
