As the name implies, a dust jacket can keep your work safe from dirt, wear and other sort of damages. The first step in constructing dust jacket is to select an appropriate paper that is similar to the book for which you are creating a jacket. Now measure the complete wraparound dimensions of the book. Cut a strip of paper that is about five inches wide, and crease it along the edges. Secure the paper in place with a clip as shown in figure 112. Wrap this paper around your book; pull it tight and tuck the loose end on the other side of the cover. All along, make well defined creases on the paper strip as you turn it over the book. Now remove the strip, and you would be able to see six distinct creases on it. In a similar manner, measure the height of the book with another strip of paper. The creases that are formed on the paper when you wrap it around have been illustrated in figure 113. Use these measurements to create a layout of the jacket on a separate sheet of paper. While doing this, measure the width of the flaps and ensure that it is almost one third of the cover width. If your book size is smaller, the flap width should be even more than this as shown in figure 114.
