I just spent this evening redesigning my book cover for Create Space, so that my eBooks and my paperback books have the same "look." It's so much easier to design an eBook cover because all you have to worry about is the front cover, and you don't have to worry about edges nearly as much. I had to rearrange my name, move over my title, etc. I also came up with a more succinct back cover blurb.
Whoops, I just remembered that my inner book pictures will have to be changed to reflect the new covers! AAAGH! That will be my next project!
