Makebeliefscomix.com's mission is to "encourage people to express their creativity through writing, drawing, and storytelling."
The site offers over 500 printables for you to use (organized by categories). You have access to what's in the news, all about you, feelings, holidays and celebrations, and many more.
An example deals with empathy and the imagining of loosing an ability such as sight or hearing and how that must feel.
Hope you can use this in some way!
