As I mentioned last night, I used 2 (I have a LOT of hair, and I'm not good at it yet). My hair was dry so I just ran a wet comb through it several times to make it damp; this was not straight out of the shower (it never would have dried that way for me, even over night). I slept fine since they were on the top of my head-- and they're soft socks. It definitely made curls! I need to practice rolling it better. I def could not wear it out as a bun. And rolling it better just means better curls, so for free it's worth trying again!
