GHD's although are straightners, they work brilliantly as curlers too!

Just grab a section of hair you would like to curl and twist the hair around the clapped ends (like you would a curling iron) then twist and pull down slowly until all section of the hair has been curled through the irons

As to making it set like Scarlets that takes hours of hair stylists :)
