Plotting vs. Pantsing

I admit it, I'm a pantster (as in, I write stories by the seat of my pants with little or no plan as to what I'm going to do when I start). But lately that's been proving problematic. Case in point, the story I'm supposed to be wrapping up this week. Suddenly, I can't remember what happens next. I can't even remember how I want it to end (beyond the obvious). So I've started plotting. Not every little detail, just general situations, notes about scenes I'd had in my head at one point or another. I'm writing them all down on index cards so I can rearrange them as necessary and see how they work. I still want the story to be fluid, but I find that if I want to keep my deadlines, I need some idea of where the bleep I'm going.  It's a new experience. The times I've tried to outline before, my characters have gone left instead of right, or worse, by the time the outline was done, I was totally bored and didn't want to write the story. I'm hoping this idea of index cards will help keep things both fluid and flowing.  What about you, do you plot out in meticulous detail or do you fly by the seat of your pants or do something in between? What are the pros and cons of each? I'll be reporting back in a month or two about how my new "plot decive" (sorry, couldn't resist!) is working.Helen Pattskyn, Fantasy Artist, Gay Romance Author
