When I use the metal clips, I've tried the kick stand thing. For me it didn't go as well. I ended up putting the clip's side flat against my scalp, so the hair was lifted straight up from there. It worked, and if I twisted the clump a little at the top it would create better root curl as well as the lift.

With the jaw clips, at least for me (and remember I'm brand new to them), I used them to just sort of "scrunch" the roots, I'd guess you could say. I won't have time today, but if possible tomorrow I'll take a pick and post it.

Again, tho, this will be my 2nd time using them, so I'm certainly not an authority! Others here would be way more helpful, I'm sure!
