Well, I personally got a pair of tweezers and one of those little shaving pencil guys with the guard (they have them at every drug store) and started really slow. First, I plucked strays. Then, I trimmed them with the longer guide on the shaving pencil thing. Then, over time, I'd maintain what I'd plucked as I brought them in (and occasionally trimming). Some girls say to never pluck from the top, but I had spots on the top that looked much better when I plucked them. I went with the generic "draw a line from the edge of your nose to the edge of your eye to your eyebrow" to determine where to end them and when working on the bottom portion, I'd decide to thin an area and once I plucked one hair from that region, I'd kind of have a guide for others that are lined up with it. The main thing was taking it slow and making sure they stayed even.
