Find a large sheet of material whether cardboard, posterboard or something else.
Find something to write with either a marker, paint or spray paint.
Look at your news and determine what you want to make a sign about. Make it an issue you are passionate about so you are able to represent the issue well if people ask you about it.
Come up with a sign slogan.
Use a pencil to draw out your slogan on the large sheet to make sure it fits.
Make your lettering LARGE -- people always makes slogans too complex so they can't be read from the street as a car passes by.
Take your sign to a protest near you!
