gabion style column - Smear concrete on stones to make column look like a solid concrete column and/or use flagstone and mortar to dress up column. Can use at end of driveway, mailbox or for backyard/gardening purposes.
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!
