Maps! Yes, you can include maps in your blog to book project.
If you are chronicling your travels in the jungles of Asia, why not include a map that highlights your adventures? If you are writing about herbs, you could include a botanical map. A book about the Mojave Desert might have a geologic map. A backpacking through Europe book could feature a road map. If your book focuses on finding the best place for expats to retire in Mexico, a climate map is an excellent addition.
If you dedicate a section to a particular theme that would do well to have a map for visual clarification, go ahead and create a map. There are several free map creator sites available online.
You can even find historical maps at Old Maps Online. Most of these maps are public domain images and free to use, but be sure to check the copyright information when using a map created by someone else.
Are you compiling a collection of Viking myths and need a map of Valhalla? You wish is granted with these fantasy maps generators.
Maps are fun to create and add a unique visual element to your final blog to book project. Make sure to save your map as a jpg or png image.
