Thread: Common stropping mistakes?

I've noticed some talk of improper stropping ruining the edge of an otherwise very sharp razor. I'm wondering, what are the most common edge killing mistakes a new stropper might make?

I mean, it seems pretty straightforward and simple, but still, I want to make sure I'm not screwing anything up. What comes to mind as the major problem(s)? Is the problem more of a "big picture" problem such as leading edge first instead of spine first? Or is it something smaller, like, using too much pressure? Or is it something hard to pinpoint, like lifting the spine up and rolling the edge? I guess any of these are problems, but what are the most common ones that really come to mind when you mention that a newbie might have ruined his shave ready edge by improper stropping?
