Do not wind the lights around, this is a common mistake that you will regret in January. You want to run the lights up and down the tree, then go around, zig zagging up and down all the way. That way they will come off much more easily (and really, go on more easily too). Remember, the lights are points, not lines. Ignore the wires and focus on the lights as points. After that it all depends on the look you are trying to achieve and how many lights you have. I like to get a multi-layered look by putting some lights deep in the tree by the trunk, some midway out, and some nearer the ends of the branches, but never all the way out at the end, that makes the wires too visible.
