sunset........
It is a good idea. I'm seriously thinking of doing the same (Not with a magic marker however)
I love my headnet, but it can be odd anchoring quickly especially as it gets colder and the neck gaiters and such start seeing action.
Plus that scratchy material always sounds like a deer sneaking up on me when I turn my head.

I'm already light tan, so it should be pretty darn easy to duplicate the ASAT pattern on my face. I'll just need the brown and black stripes.

I am going on a big hunt soon and am trying to eliminate all possibilities of scewing it up.
