Leaflets are useful when you have a chance to hand them to people. They are less useful if they are left to be picked up.
The more interesting a leaflet is to the audience, the more likely they are to read it. Try to reduce the words used. Have photos or other images that will be of interest to the audience.
People are more likely to be interested if they know it has been produced by students.
When you provide information in pamphlets make sure that you are accurate with your facts. Explain that it is your opinion, when writing about your opinion.
