I usually give myself a mark and shave, take care of the sides, my little uni-brow sprouts I get rid of them, make sure the middle evenly spaced, take off any unwanted hair around the top of my eyebrows, to the ends and not much under them. Got quite a few cuts learning to do this with a wilkinson razor blade alone.
The hardest for me was to keep both sides even and get the area behind my ears.. On travel I use a panasonic shaver for the heavy stuff and a wilkinson blade mated to one of those safety shavers like this

Usually takes 20mins or so for a full mark, eyebrow clean up and shave, saves me the 20euro price by the shops
