Here is another fascinating Book Deal blog about ways to thicken your plot.
I said in an earlier post that in revision what I find is generally too much plot. Anyone who's done Nanowrimo will recognise the casually tossed in and incongruous plot twist used to liven things up when your energy level is flagging. I make no apology for this. Writing a first draft is like running a marathon and at times you will try anything to get some momentum going when your ideas have run dry and the characters are standing around looking for inspiration.
But that's the great thing about revision. These things are so easy to spot and easy to deal with, assuming you are ruthless enough. All the daft stuff has to go. I find I can usually remember what I was thinking when I made Dorothy, the one legged trapeze artist lover of Quentin, the Main Character, pull that sabre from her knickers and chop off the heads of all seven of their party guests. I was tired and bored and itching to write something exciting for a change. But let's face it, it won't really play in a Romcom now will it? So the sabre, the party, even Dorothy have to go. Yes, I know it was a week's work, but it's contrived, it deviates from the plot and frankly, it's dumb.
If it means losing a lot of material then so be it. The point is to carve out the excess to reveal the story and bring salient plot points to the fore. New scenes will present themselves - I have a constant struggle to stop myself rewriting nearly every scene. The revision is hard work. It isn't just a bit of nip and tuck.
