At the base of my neck I've got hair going up in the middle and to the sides going outward. Sort of like this:

--------\\\\\//////---------
--------\\\\\/////----------

So I go WTG 1st, then ATG in the middle and sides, then after I rinse I stretch the skin and listening to the blade as it picks up the strays.

I'll run my finger over the hairs to raise them and then cut them before they have a chance to retreat!

Stretching is key, pull the skin next to the adams apple to one side while you shave to avoid cuts since the skin is susceptible to cuts in that area.

Hope that helps.
