Cross wrapping is another option for wearing your hair to bed. I rarely wrap my hair but when I do, I cross wrap rather than doing a regular "doobie" wrap. I prefer to cross wrap my hair because regular wrapping makes my hair limp and it causes my hair to "bend" in the direction of the wrap. The bend makes my hair look uneven or slanted from the back. With cross wrapping there is also less tension applied to my ends and edges.
I hope this is helpful.
