Keep it simple. "READ" is the message. Reinforce the message with a followup line. This one resonates with teens, teachers and others who have enjoyed reading Suzanne Collin's The Hunger Game series: "May the odd be ever in your favor." Combine and wear the message! T- shirt advocacy is a practical and fun way to start a conversation or make others take a moment to think about the message.
The California School Library Association Foundation's Library Store offers a variety of items with this message at cafepress.com/csla, including wall peels (like posters but no tape is needed and no harm is done to the wall), mugs, journals, and all sorts of gift ideas.
