Genre

According to various websites and my own experience of what a good flyer is, it is not very hard to create an attractive flyer if you put effort into it. Some fundementals for flyers are to be very conservative and economical with your text. If you hit a reader with a wall of text they will probably go "tl;dr" (too long; didn't read) and toss the flyer away. It is important to keep in mind the age old cliche " a picture is worth a thousand words" and in the case of flyers pictures are infinitely more important than words. However, everything must be done in moderation because if you put too many pictures and enough words then your message might not get across. Simplicity is also a key factor in making a good flyer because fundementally things that are simple are easier to understand in a brief amount of time. This is important because if you can have the reader understand what your message as they recieve the flyer, the more likely they are to react.
The people that write in this genre all people seeking to advertise something. Another reason for using flyers is to increase awareness for a cause. I have as much freedom as my imagination allows considering my genre.
