Neighbours have just changed their fence, it’s the one at the back of my garden so don’t know these neighbours, the fence is ok height but the top bit is that trellis thing and as we are on a hill it means they can see into mine as my house and garden slope down, I don’t want to attach anything to the fence as obviously it isn’t mine I have some trees at the back is there anything I can attach to them so they can’t see in? Or any other ideas?
