Andy, I made mine to ` follow` the line/s of my own temples and down the ear flaps....... I originally kept a very small amount of my growing hair at the nape and directly in front of the ears, but this did not mean I made the template ` smaller` there [I have since shaved it all off] --- I made my best guesstimate of the coverage I needed and made the template to that shape/size......... I just took delivery today of a new Toplace Fullcap...... will have it cut -in shortly and will post pics........ on this latest system, for the nape, I used this thought: I wanted the finished [cut] hair to be no more than 1/2 an inch ` below` the perimeter, so that it doesn`t tend to stick out, as shorter hair tends to ` sit-in` properly against the skin there..... if you can mark your neck with a horizontal line,representing where your hair will ` end`, then come up from there with another horizontal line which will be where your perimeter/edge will sit.... somewhere between 1/4 of an inch to no more than 1/2 an inch max. between both lines......the general guidance for the nape area is to have the perimeter sitting just under the occipital bone [the circular bone at the base of the skull] ...in my case, I find it best to come ` down` further.....you`ll have to use your own judgement on it...... I also find it best to keep your perimeter ` down` just behind the ears too--it helps the hair to curl inwards towards the back of the ears...if it`s a bit ` high` it can look a bit odd. Hope that makes sense /hasn`t confused you.
