Yesterday I talked about using a visual clue for section breaks other than an addition space. One way to enhance your book’s interior is to use a glyph that relates to your story instead of asterisks. Making them a part of your formatting adds a nice, thoughtful touch that adds to the flavor of the story. For example, if your story is about a horse, you could use a few horse shoes for section dividers.
There are many options you can explore in unicode and wingding fonts which are easier to use overall than a jpg file. One drawback of jpg files is their resolution, which to show up clearly needs to be at least 300 dpi for print. I don’t know about your word processor, but Word isn’t very cooperative for this and tends to reduce them to around 200 dpi. This then requires replacing them in the final pdf file one by one, which can be onerous, to say the least. Some print on demand publishers may not care, but some like Lightning Source and Ingram do, and will bounce it back. Thus, if it’s part of a font set, this is not a problem.
