I have to agree with Vaughn. First and foremost I try to get my sanding as good as I can get it. Several pieces I have started over from 80 grit and worked my way back up. Mostly when I find myself trying to press real hard on the sandpaper like that is going to cure it all. As I have progressed over the last couple of years my tool control has gotten better and better so tool marks are not as much of a issue as they used to be. I think turners are our own worst critics. When I first started maybe 1 in 5 pieces would pass for what I might sell even though my wife said all looked good. Now it is 5 pieces pass and 1 won't. So as time goes on and your technique gets better it will all work out.
As was said in the other post and as Vaughn said some people will pass things with lower standards. When I pick up pieces at these craft fairs with tool marks, sanding marks, or the finish is sagging or uneven I would be embarrassed to even show those things. But that is just me. In fact I probably wouldn't be at the craft fair in the first place with pieces looking like that.
