We recently came upon a great article by Hoeffler & Frere-Jones about combining multiple fonts in a single work. We work with fabulous designers who know how to combine fonts in their sleep, but in our own lives and personal projects, we are always on the lookout for nice rules-of-thumb for graphic layout.
Hoeffler & Frere-Jones present four palette concepts, each complete with short, compelling descriptions and shorthand for roles that the fonts play. My favorite concept is 'wit', mostly because each of the font roles is broken into 'tough', 'cheeky', and 'sweet'. There are already some Christmas gift applications coming to mind!
Perhaps with the concepts from H & FJ, you can make your own newsletters, birthday cards, and other projects have a bit more impact, too.
