So I'm finally getting around to doing it myself. I need practice. It's horribly apparent (in a rush too..the parts are awful LOL). But it's DO ABLE on her thin/short hair so I'm excited.
Do a top part all the way across her hair and put a pony on one side
Then do another part all the way across and pony it off to the other side..Then repeat. It works well to get your part all combed and nice looking BEFORE adding the previous ponytail.
