Illustrator was the last of the Adobe big three programs that I learned. But when I did, I fell in love with it. I just started playing with it and expanded from there. Vector art is the way to go, especially when creating logos. But it is also trendy now in advertising. Colors stay true, and you can use a piece of vector art as large or tiny as you want without losing quality. Below is a small sample of designs I have done over 24 years.
