Don't think I would go that route. Sounds like a lot of work, would be less natural looking, and a pain in the butt whenever a piece of fishing line breaks, and trying to hide the fishing line which you would inevitably see. I would probably remove those rocks you have now and replace them with larger, flatter rocks that would stick out a bit past the top of the pond liner. You can always put many of the round stones back on top if you like them, but rather than creating a ring around the pond with them, I would suggest a more haphazard placement to make it look more natural. I like the way you piled them up on the fence side. Also, it looks as if you pond water level could be brought up quite a bit. Whatever you decide, post pics of your progress. Good to have you with us.
