We are almost done with the steps. Here I've set the brick (actually faux brick pavers) edge in sand, angled slightly to form a rim to keep the gravel in place. We need a few more bricks.
Below, we are screening the gravel to remove some of the subsoil.
With the gravel added and some sand filling the cracks.
We will fill in the cracks with a mix of compost and sand, and plant some thyme.
