Congratulations Montana, good job. Yes, it takes awhile to learn all the different directions hair grows on your head. In time you will get it, I do mine by feel. I thoroughly enjoy the process and time it takes to shave with a double edge razor. Some things that work good for me is exfoliating a couple times a week, cold water finish, and refrigerated witch hazel.
FYI, you can get 100 Astra platinum blades on Amazon for about ten bucks.
