What I would like to be able to do is make a mold of my head then some how get a styrofoam made of my actual head size. Then make the templates from the styrofoam head. That would probably be the most accurate template you could get.
I know try as I may to get a full cap template perfect I will get the area over the ears too tight or the temple sideburn area off. I did order the plastic that shrink wraps. Look forward to giving that a try. Will be interesting how that goes. I ask the company that was mentioned earlier that does a "custom fitting kit" if they could just make me a template from the kit measurements and not make a hair system. They said never been asked that question before. I wait to hear their reply. Their systems are a little rich for me.
