Have a look at the thread `` Short video of template-making/attachment`` a few steps down the page there........ Bobbyphilly posted a link there a few days ago ....VERY useful and informative showing michiganbaldie going through several steps including a 9-minute clip of how to make a template......that should answer your questions for you. There is no need to measure your scalp--the system is made to the exact size of the Template. Regards, Paul.
