what size/color are you using and are you doing it wet or dry?
I use the red ones and when i do it on dry hair i use 7-9 and when it is wet i use 12-15 for tighter curls. There is a picture in my fokti with the rods in
I checked all you guys fotki, It looks like to get thighter curls you need more rods and less rods looks more wavy. Will try both and see which one I prefer.
