It's true there are at least three other ways to do this that I have tried, all of them work well and produce about the same kind of result. I wrote this one up for people getting started to have a simple understandable method.

Using layer styles, strokes, inner or outer glow, and contours are among the more complicated ways. I may decide to write up more of them if there is enough interest. I know when I started, I hunted for quite a while before I actually figured out this method, and then later some other friendly members showed me some of the other ways. So at least with this, newcomers have a quick and easy way to get started
