Hi Dino, I agree..... I`ve found that by bringing the perimeter ` down` further below the Occipital bone [for newbies--
that`s the round bone at the base of your skull above the neck area] I can then have the hair relatively short, as in your pic.
and it then tends to sit `in` against the skin in a natural-looking manner.....the longer the hair in that area, the more it tends
to curl outwards, which is a real give-away. I suppose too, that not everyone`s head-shape /size is the same, naturally, so
the occipital bone will not be located in exactly the ` same` spot ...some people will have it a little higher up from the nape, and others
will be a little lower down........ I think it`s best , when making a template, to just gauge where you think/know your hair naturally
` ends` and have your perimeter just a few millimetres above there, for a natural look. Lovely -looking system--enjoy ! Regards.
