Hey mate. I wear a full cap and it isn't as daunting as you may think. Regarding a template I did it with kitchen wrap and sticky tape, it is a little time consuming but well worth it. You can do it by measurements but then the temple points and hairline shape are left up to the person making it. Attaching is easy after a couple of times. Look up Jrob's website/blog, type it into google. There are instructions there. What I say to people going to a full cap is to try it with got2b glued gel so you get a feel for it and how to attach. Go for all french lace mate, your age around 70% density. Good luck fella
