New to straight razors, and climbing the learning curve, but taking my time and keeping it enjoyable.

My current dilemma: I can't see SQUAT when trying to get to my sideburns, (about 1/4 inch below where ear meets my head). I've been trying different angles... mirrors... grips... and nothing gives me a good clear view of what I'm doing. It seems that whatever I do, my hand or razor is blocking my view of where the blade should be contacting my skin. Am I missing something? I wear glasses, another obstacle to dodge, and am left handed, but with good control with right hand. Plan "B" is to grow the sideburns longer, but that's admitting defeat. LOL
