Do this. Especially if you are new to fandom--this is the perfect size for starting out, and on the whole, it's pretty low stress.
Me, trying to decide if I should do this one or not. I still like the one I did last year, and the one before that. *sigh* I'd almost decided not to but I keep getting this single image of the car, Sam sprawled in the passenger side, sweating from the heat as Dean drives aimlessly. Kind of like my life. :)
