In one of our classes, the main project was to produce a class made magazine. We were all split into different groups to handle the major design decisions, and my group was tasked with creating the style guide. This included obvious things like the colour pallet and typefaces, but also more subtle things like tone of voice, and use of space. Many examples were included to show both what was acceptable and unacceptable, as well as wire-frames to help provide as clear a picture as possible to the rest of the class.
