Not Nick Ovel

How does one cut the rearward hair on ones head?

Putting it in a ponytail and just chopping "some" (for a given length of some = N - Ideal length + Poor eyesight / scissors + left-handedness) off has resulted in the wierdest mullet ever! No business in the front whatsoever, with a party in the back and the sides...well, a great big ginger party all round....especially in back.

O.o

Can someone please give me a "do"?
