For my online font library I decided to explore Adobe Typekit. Typekit is a great tool for graphic designers and other designers who use typography.
Out of all the fonts this online library has to offer I chose Paralucent Medium and Mr Eaves Modern. Both of these fonts are San Serif but I think they work well together (as seen below). The Paralucent font is bolder and has a curvy feeling, while Mr Eaves has a more rigid and straight character. These differences create a hierarchy when used together, as seen in the sample heading and sub-heading. These fonts could be used together in a potential website!
