I have a lovely long dry stone wall. I would like to add some height to a section of it. Which is next to my neighbours much higher level patio. My side is cobble stones. I think I'm creative but I'm stumped on how/what to do to get the privacy I want/need. It's not a small section so a line of planters would be £££s. I'm thinking some kind of trellis thing but I'm pretty sure I wouldn't be able to attach anything to the dry stone wall. Plus, ideally I don't want to cover the wall. I had hoped the neighbours would put something up their side...alas I very much doubt this will happen.
