Sometimes you will need to include annotations to be sure your wireframes communicate enough to others who are looking at them. These are particularly good for describing things that cannot be easily communicated such as needs that must be addressed during visual design or guidelines for what type of content can be used in a particular position.
When you add annotations, there are few things that can be useful:
- Numbers and Titles
Adding numbers and titles (as in the example below) makes it easy to refer to annotations when discussing them with others. - Unobtrusive Arrows
Your arrows pointing to page elements should not interfere wit the wireframes themselves.
