Book covers. This is where I like to have complete control. Maybe not do the actual design myself, but to puppet a talented artist to do it just the way I want it. I used to dream I'd have Michael Whelan as my own personal cover artist.
All the books I've self-published, I designed the covers and I'm immensely pleased with them. I bought the images from a host site (Dreamstime), and I manipulated them to suit the stories. I spent as much time on the font as the images themselves. It's tough work making a cover perfect. It takes a long time. Time I'd rather spend writing.
For my Dice & Debauchery books, I have very little input on the covers. I filled out a questionnaire and described my main characters, but that's all the say I get in it. I knew I wouldn't have any control in this when I signed the contract. I weighed it against the benefits of having a publisher for this series. I'm keeping my fingers crossed that I at least kind of like the covers when I see them.
Next year, I'm self-publishing an urban fantasy novel. I'm going to hire a cover artist to do it for me. I'll have much more input than I do with my publisher, but not as much as I do if I did it myself. I tried finding images that would work for a cover, but nothing stood out for me. Nothing I wanted for this book. It has to be unique. It has to be made to suit it.
If you're published, did you design your own covers or did someone else? Do you like having control or are you much more easy-going about it than I am?
