Fonts are really important to print and web design. They can either make or break a design. Sometimes, I get into a rut and start using the same fonts in some of my projects. I admit that I've abused Century Gothic more times than I can remember. To break free from the Century Gothic overload, I go online to my favorite font websites to download the ones that would be a perfect fit for my work. It's important though to not get side-tracked by the pretty fonts on there. There are a lot of trendy and awesome looking fonts on these sites, but it's important to pick one that would best visually represent the kind of message you want to convey about your client's business or image.
