Susan in Birchgrove got a new dog, a little toy poodle. She worried that it would fall between the balusters. The solution had to be affordable, practical and still look good. I installed pvc plastic sheets, cut to fit, all the way up the stairs. (The TV image in the photo is a reflection from the clear plastic.) Susan was pleased that they were relatively unobtrusive and easy to remove. Just clip the white cable ties.
