This one is pretty easy.
Part the hair from her temple across her head to just behind her ear. Pull smooth and secure with an elastic on the side opposite the temple where you started.
Part down from the temple and pull it across her head to just next to the other side. Comb smooth and secure with an elastic only this time make the ponytail off a bit from your first ponytail.
Repeat until you get to the bottom and the last elastic.
At this point you can do what you want. You could do a flippy ponytail, you could tie a bow, you could curl it. This time we kept going until just before the end. I should have curled the end but I am lazy today and didn't want to go all the way back up the stairs.
By-the-way, today we used ouchless covered elastics. Her hair is getting too thick for the plastic elastics.
