I make four braids (plats) going towards the back and I pin them up before going to bed. I make my braids on hair already dried rather than on wet hair. After only an hour, I can get nice, soft waves - tighter waves if overnight.
When I first posted this pic in my album in 2004, some of the ladies said it looks like a pretty style so now I wear this as an updo and take it down if I want a braidout.
