Ok, I think you are talking about the spiral set where half is blue and the other half of the spirals is white right?
I have those too. You have to take small sections of your hair. Take one section and take a spiral, you want to place the hook at the roots of your hair section, then you take the hair and put it on the spiral and just keep putting it around and around until your ends. Then you take the clip and place it right over your hair ends. Sometimes, when the section is too thick (meaning you took too much hair) or if your hair is too dry (it's better when you spray it damp before starting this), the hair comes out of the clip. You don't want that. So make sure you take the right amount of hair, you will get better after you do it several times
.
Good luck
