I have thought about that, and I am trying to be veryyyyy careful and do it evenly, but if I screw it up I did at least learn one thing..... not to try that again..LOL But seriously, It is working so far, and I have trimmed a fair amount. Little by little I will keep going until I don't see results, I ruin it, or I get scared , chicken out , and settle for what I've done. We'll see.
