Stropped my 6/8" Dovo (full hollow) for the first time today (2nd shave), and things seemed to go well. A few passes (~20) on the fabric side, then more (~40) on the leather, with lots of pressure on the spine, but hardly any on the edge. The shave went well, and then I stropped a little after (not as much as before) to make sure everything was clean and dry before packing away.

The thing I don't know is how do I know I did it right? How do I know I didn't cause damage?

What can I use as feedback to improve my technique?
