its easier to do it on someone else. i got a dvd with my ghd's that shows you how to get different styles and that was quite helpful! i don't really curl my hair with mine but i do make it wavy. i used to think it was really hard and then i got a set of babyliss curling straighteners that have curved plates to 'make it easier' but i couldn't use them at all and i ended up taking them back because i didn't think they were as easy to use as my ghd's. just try practisicing and after a while it you might find it easier to do
its really simple once you know the basic concept by i would look on you tube....there are loads of tutorials also its easier to practice on some1 1st to get the technique then try it on yourself
