There are two basic formats for writing a booklet. The first is the tips format. It is very basic and simple, being filled with useful tips which are almost like bullet points. The tips format is handy when you’ve got alot of content to cover and you’re teaching something.
The narrative format is longer and should draw the reader into the text. It is more explanatory in nature, and focuses on a single subject.
My own style leans more toward the narrative side, although I frequently use a combination of both in the same booklet. And my three hottest sellers are really neither of these styles, though they do contain both narrative text and tips. They are recipe booklets, and the bulk of the content contains recipes.
There are no hard and fast rules here. You can write in your own style, as long as it makes sense to your intended audience. What matters most is not the format for the content, but how compelling the content is.
