i discovered a way that will give you that jes du ragged for the whole night look in jes a few minutes and w/o the appearance of that MEAN line. there are a few things that you will need:

2 du rags. (preferably spartan stretch kind)

some form of moisturizer.

spray bottle.

blow dryer.

the first thing you do is put some kind of moisturizer, pomade or grease in ur hair. w/e will make it soft. then you will brush how ever long u usually do. after this you will spray hair wit water bottle till moistened all over. apply du rag number one(dont be afraid to tie it tight cuz it will only take a few minutes). spray this one with water. (abt 10 squirts on back, front, and sides). then apply du rag number two and spray it the same way. once this is done, u can get out the trusty blow dryer and use till u feel as if both du rags all the way to the hair is dry. when u take off the du rags, ppl will think that u du ragged for an extended period of time. but look ma'... no lines!

or u can jus wear the durag inside out,  like i do,

and i neva have a line.
