Doesn't seem like much can be done for these "age lines" in the top. I'll just think of them as smile creases from good times with the top down more than its up.
Actually, there was one suggestion in that thread about using Downy to try and lift the crushed fibers. I'll see what the Raggtop folks say about it.
