Subplotting

So by now I'm sure I've talked about having to rewrite the last third of my book about a million times. But it is my main focus (except when I'm distracted by shiny sequel ideas) so what else should I talk about, right? But the whole rewriting thing isn't just about the main plot. There are some changes happening there but it basically follows the same path. I do have to rewrite pretty much everything, but there aren't a lot of major changes. Where the bigger changes are happening is in the subplots.

Subplots can be tricky. They have to make sense within a story. You'll probably have to ask yourself if the subplot you're imagining is really necessary. If it feels forced, then it may not work. It should compliment the main plot in some way, or at least make sense for the characters involved. And obviously, you don't want it to be boring. You don't want the reader to be bored while reading the subplots and just flying through the pages to get back to the main plot.

I have two subplots in Uneven Lines (because I'm a crazy person who didn't think the main plot was complicated enough, apparently). I think they work because they focus on the main character's relationships with the people he interacts with every day. So there's a subplot regarding Jordan's mother and another that involves his friends. I think you can have characters popping up now and then without having their moments evolve into an actual subplot, but in these two cases I feel enough happens that they can be called subplots.

But like I said at the beginning, I am rewriting these subplots as part of my overhaul of the end of the book. I felt like they were weak in the previous drafts and that I was forcing certain moments to where it didn't really make much sense. So I'm trying to figure that out. It's tricky trying to figure out how to make every single moment not only believable, but also relevant to the story. I've mostly figured out the mom subplot, although I do feel it ends a bit early. The friend subplot is proving more difficult. I think it's because it's becoming a lot more elaborate than I initially intended, but I think that's a good thing because it reflects the main plot more. Jordan is the type of character who always has some kind of scheme going on, or in this case, two at once. It's just tricky trying to map out that scheme so that it makes sense.

But here I go rambling again. How do you guys work subplots into your stories?
