[SigilBear]

Apologies for a long-winded question(s), but any tips at all would be helpful. I suspect this question has been asked before, so maybe someone could just point me to an existing discussion or a relevant article on another site.

I'm new to epubs. I recently started out working with InDesign, but I found the learning curve pretty steep, plus I was amazed to learn that you can't work directly with HTML. So I switched to Sigil, which I love, except that you can't put subfolders in the Images folder, which is why I'm going to check out Calibre. I also need to learn how to work with iBooks Author, as I hope to create versions for both Amazon and iBooks.

I also want to learn how to make fixed layouts; I've only made reflowable epubs so far.

So here's my question: What would be a good work flow if I want to create FOUR versions of an epub, as follows:

1. Amazon Kindle (reflowable)
2. Amazon Kindle (fixed)
3. iBooks (reflowable)
4. iBooks (fixed)

I assume it's generally easier to create a reflowable epub, then convert it to a fixed layout, rather than vice versa.

But is it easier to create a Kindle version, then convert it to an iBooks format, or vice versa?

I think I read somewhere that you can import an epub into iBooks, then convert it to Apple's format. I haven't yet learned if you can do the opposite - import an epub made with iBooks into InDesign, Sigil, etc.

If iBooks gives you access to the HTML, then I'd be tempted to create a fixed layout in iBooks first, then somehow convert it to an Amazon Kindle version.

However, I'm going to begin by creating a simple website in Dreamweaver, which I can then import into an epub program (Sigil, iBooks Author, etc.).

Thanks for any tps.
