I parted the hair down the middle. This doesn't have to be perfect - just kind of loose looking. I twisted one half of the pony tail.
Twist the other half, also.
Bring them together in a pony tail with an elastic.
Grab a piece from the pony & wrap it around the elastic so you can't see the elastic.
I use a clear elastic at the very bottom of the wrap to hold it in. It works great & you can pull the hair down over the clear elastic to cover it up.
You can curl the pony or just leave it as is.
