Ok, I guess the more the merrier, the limiting factor being how much of it I can tie into a coherent story.
I assume you're talking about flashbacks where time goes forward in each flashback, and your concern is what order to put the flashbacks in.
Yes, that's what I was trying to say. I was afraid if flashbacks in reverse order would just confuse the reader: in each subsequent flashback you expect to learn what happens next, but get to know what happened before instead.
I asked about flashbacks on my blog, and there are a few comments.
The technical thing I've seen writers talk about the most is point of view, which I suppose is easier because it can be addressed at the sentence level, but possibly there should be more about wrangling chunks of story.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
