answer:First, make sure the flyer includes the following: A headline (Come up with a catchy phrase that makes people want to find out more such as “Make a Difference: Join Project Letters to Sea” or whatever your program is called.) A brief (say a paragraph, two at the most) description of the project. Then, include all the facts a person needs to know to participate. Dates the project will run, who they contact to get started, what they have to do to sign-up, etc. Finally, end the flyer with what the marketing and sales folks refer to as the “call to action”. That would be a brief statement of why someone would want to participate. In this case, the things that come to mind are phrases like: Help support our troops. Your letters can really make a difference for someone serving our country. Sign up for Project Letters at Sea today. (your words, of course) Add some artwork and leave some white space. Make sure the flyer is not too type heavy so people are not turned off before they get to the end. Sounds like a great thing you are doing. Good luck.
