Any hairdressers/barbers on?

I want to cut my own hair with clippers, short all over (like a 3), best way i can describe it is like Justin Timberlakes. Whats the best way to do this?

Start at the front, work slowly towards the back. Once you have done whole head work in the opposite direction to get all the missed bits. May be better to have a friend do over the back for you. If your hair is quite long use grade 6 first then use grade 3.

Front to back, all over, then check for the long bits you've left!
