I've gone through Summon the Seasons once for a developmental edit, though I have a feeling there may be scenes that I'll want to revise again before I'm satisfied. In the meantime, I've been formatting the manuscript. I use a template that I bought from Book Design Templates. It's simple to use and works for both eBooks and paperbacks. I still have to comb through the manuscript to make sure everything looks right, and I always order a paper proof to check formatting. Formatting gets easier with practice, though.
How do you format your books? Do you use a special program or work with Word? Do it yourself or hire it out? Feel free to share in the comments.
