I almost forgot:
1. I use Optivisors because I just don't see as well as I did when I was 25.
2. The master lines are THE most important lines in the pattern. If they aren't straight I'll guarantee the rest of your lines will not get any better.
3. This is a hard concept for me to put into words, but you almost have to see where you want to end up with your line and sort of reach for it at the end. This will help you avoid pinching the ends of you lines. I told you I wasn't going to be able to explain this!
