Start by putting your hair into a ponytail
Separate your hair into 2 equal pieces
Grab a small piece of hair from the outer chunk of hair
And bring it across, and then add it to the other chunk of hair.
Then grab a small piece of hair from the inner chunk of hair
And bring it over to the outer chunk. Keep doing this over and over and over again.
Go until you have an inch or two left at the bottom, and put an elastic around the bottom of your hair.
And then pull on the sides of your braid to loosen it a bit.
And here's the finished product
