After logo design, creating posters is my second favorite thing to do. Here are some poster design rules I always try to follow.
• Limit your text and use no more than two font types and no more three font sizes.
• Choose an image or two that portrays your message well.
• Don’t go overboard on color.
• When it comes to the layout, leave lots of space.
• Design more than one layout.
• Break the rules when possible! ;)
