I want to chime in but not hijack....I have been maintaining my rollersets by putting my hair in a very high ponytail (I use one of those ball barrettes so I don't have to drag my hair through an elastic band), smoothing down the length, then using my fingers to roll the ponytail into one big, tight barrel pincurl. I pin it with two long bobby pins and cover it with a hairnet. The next day I release the ponytail holder and I have a giant spiral curl. either comb through or finger comb and the lower 2/3 of my hair is curly curly curly. I fluff the top a little bit for height but I am going to try the bantu knot method to see if I can get an overall curly look.
