Hello Paul,
I trimmed it just a little bit, but not much. There's hair beneath, actually, it's hair that didn't fall completely but became "baby hair"... you can't see it even without the template if I shave. I want to reconstruct my hairline, so perhaps I should leave it.




It doesn't stay 100% flat around the flaps anymore because I added too much tape, I think... I'm assuming this isn't an issue since it's just a guide.
