I am a fan of the brittish show "Celebrity Scissorhands" and recently saw this on You Tube and had to link it here
I am ready for a haircut and am thinking that I might have to do this.
Apparently the more you pull the pony tail forward the more layers you get and then you cut into the end of the pony edge or "shaving brush" as it is reffered to and it gives you the choppy layers.
So depending on degrees you could have very gradual or almost no layers at all.
As I said before, I really may have to try this as my hair has almost no body at all.
