If you have good hair in the nape, I think it's not a bad idea to leave that hair. If you don't, I think you can just shave it all off or use concealer to thicken the nape hair. I currently use about a half inch strip for the nape. I use concealer to thicken that strip. It's not a perfect solution, but it's pretty good. Why are you considering making a change in your template?
