DIY - Homemade Gabion wall ie rocks encased in wire baskets and used as a retaining wall - creates a dramatic feature in a garden. No directions on link. Nice someone figured out how to landscape with river rock. I swear they grow!
For the beach house* river rocks in a box + garden hose = clean feet what a great garden idea! Placed in the sun will heat the stones as well. Great way to wash off little feet covered with grass and dirt before coming inside.
