I didn't take as many pictures as I should have with this one, but I'll walk you through it!

Start off by parting half of the hair from ear to ear. Then tie off little sections. Next, do the same to the top. (This is where you can get creative.) I did straight parts on bottom, but a grid on top. You can keep this simple and just stick with straight parts if you want.
*Sorry, This is where I should have had a picture without everything connected. At this point it should just look like a bunch of sectioned off pieces, and the hair should just all hang in little ponies every where.
This part looks tricky, but it is really simple. Combine the top section and bottom section, by twisting once and adding in to the next section. Meet the sections at the back of the head and tie off with an elastic.
