Russ has a great suggestion, but if you're looking for quick and easy, and all you're doing is their names, type their name in Word using "stencil" font. After that, you can outline the letter and change the inner color to white. Makes for fast lettering.
Bill, who's going to try to be serious from this point on....not.
P.S. You don't have to use "stencil" but it prevents "floaters" on the lettering. If you do a two-layer project you can use any font. I do that and it gives it a look that a lot of people really like. Good luck!
