As you might notice from my sudden spate of new topics here, I'm quite busy in my new shaving hobby. I have a poor man's strop that had to be replaced because of wrinkles in the leather. I still have it and would like to do something with it. I think it's a good candidate to turn into a pasted strop, but I'm not sure if it's a good idea.

The strop has some wrinkles that are a little rough, and 3 or 4 nicks. Only one of them is noticable to the touch.

If I were to slather some paste on this, will the paste cover up the imperfections? If not, should I sand the leather to get a more uniform pasting surface?
