So I've shaved half a dozen times with the razor I got off Scott, I've been getting better at sideburns and tried to tackle my chin yesterday, I managed to shave it but the bit just under my chin was kinda poorly done.

Now I had been looking about for info on it but there seems to be no information with regards to shaving your chin besides "make the skin taught". Is that all i need to do?

Also should i be rolling the razor with my wrist or fingers as it follows the curve of my chin?

And another thing, how do people look at where they first start shaving? As in at the very top of where your sideburns grow, my arm blocks my vision when i put the razor in place so the first few strokes are more or less blind, any pointers would be much appreciated. Should i be shaving the right side of my face with my left hand? At the moment I am doing right with right and left with left.
