Blank White Cards Template (424kB PDF)
I like this because it lets me draw the cards on something a bit larger (instead of a smaller piece of paper, there are borders on the edge (my scanner crops a couple of millimeters off the top of each scan if I line it up with the top edge, and I can put them in a binder for later viewing/scanning.
Perhaps not so cool for the actual playing of the game in real life, but perhaps I can keep a duotang binder with me and doodle away and slice everythig up later.
The PDF file is too large, and I'll be taking down the link when I run out of web space. I just thought I'd share this with the group.
