Think carefully about Your Book's Spine.

The Spine can be a problem if you do not keep it simple:
If the spine is thick, put the words of the title upright. On a thinner book, run the title down the spine with the top of the words toward the front cover. Make the title readable from a stack of books on a shelf. Do not over-fill the spine with color, images, or confusing lines. Above all, do not stack each letter of the title on top of each other.

KISS: Keep it short and sweet. A glance at a row of book spines may be the only chance you get before the reader moves to another row.

If your name will also fit on the spine, include it. Simple works for the spine. Save your creative ideas for the front and back covers.
