I'm new this and I'm trying to figure out how to stack words using two different colors. What I'm doing is for a race car. He wants the Bottom color black and the top color to be blue. How ever i'm not able to figure out how to figure out the size difference between the two. Can anyone please help me out?

I'm using Vinyl Masters

Ok I have been on you tube but having a hard time finding them. I have spent probably an hour on my software looking for it and I'm not seeing it.
