One area where I have trouble. I still have a electric razor and may do this until I get the hang. I have a chinstrap beard with a goatee. So on top part of my upper lip I try to make a separation between the top of the lop and bottom of the mustache. I can do it with the electric and the DE. Trying to get it with a straight without cutting the mustache or my lip seems impossible. How can I do this? I was able to get between my nose and the top of the mustache no problem though.
