A brochure typically has three panels. The first panel is the outside, or front, panel. This is where you make your key sales pitch, grab the reader's attention, and explain what the brochure is about. The middle panel is the inside, or back, panel. This is where you provide more detailed information about your product or service. The third panel is the flap, or pocket panel. This is where you can put additional information, such as a coupon, order form, or map.
