I see you responded to my post that’s no longer here. Thank you for your words of encouragement.
For the eBooks that I put on Amazon, I used Kindle Create; I take it that it reformats the word doc into a mobi file. And then I had to manipulate what showed up in Kindle Create to make it look that way I wanted it to look. Mostly it turned out just fine, but it didn’t leave the chapter headings or the title in the font that I had chosen. But it still looks good.
