Hello, I have a low retaining wall in my garden which surrounds a patio area. It would be useful to turn it into seating but not sure how to do this or what to use. It is about 12-14 foot long, built from stone and well built.
What can I use on top to turn it into seating? Is wood the best? What do I do to make sure it doesn't slip or fall off? Do I use brackets?
