Thinking of doing something like this in the "path" we always walk on across the lawn. It's getting worn down and I can't get everyone(including myself sometimes) to go around on the sidewalk. Step-by-step: Flagstone path
Love the half wall and iron with pillars. Got to do this on the side of my patio area from the house to the back fence using cinder blocks and short wrought iron fencing from Home Depot, cover with stucco, add light posts on the pillars.
