Gravel around the foundation for drainage, plant shrubs along to help soak up water. Like the idea of the large rock to prevent erosion from the water spicket. Maybe a few cool pots or barrels with plants too? I like :)
The chinese knot is flatter than the French knot, more shapely, not so twisted. In Chinese embroideries it's seldom used as isolated stitch but generally massed together, often covering large areas.
