So, this started as being Mermaid hair, however, looking back, it certainly looks more like unicorn hair. Take a thin cross section of hair and secure with elastic. Next take another small cross section of hair below the first, include the first pony tail and secure the second. After the elastic is on, pull a little of the first pony tail back out so it kind of puffs up. Now continue with the third and forth in the same way until you are finished with the head area. Add more elastics on the pony tail, roughly the same spacing, before adding each additional elastic pull a little of the outside hair to puff it a little. If you want you could add a little padding like cotton balls or tissue or nerf ball, get creative!
