Wow, it's been a hot minute since I've been here. I have roughly knee length hair and always throw it over the top of my pillow when I sleep, no braids, just toss it over the pillow and go to sleep. I've never had any problems or even bad tangles, and it's still growing longer, so I guess it can work. When it was shorter I'd just toss it to whatever side I wasn't facing until it got long enough to stay in place.
