5 flat twists going back. We had a family emergency...while waiting in car for mom to come out...I did this. Took 5 mins to do, 1 min per twist. Then when emergency was over...tied it with a scarf. Will last for a week then a twist out!
If you need to look presentable with no time to do it in try this. It does not matter if hair is strait or curly, although curly is better cuz it won't unravel...my hair was in a power puff before I did this. If you do this with strait hair, use gel and bands, clips, or barrettes to hold in place.
