DIY Cinder Block 'sofa': TI love how this cinderblock sofa almost takes on a kid-like quality. It's like it's built out of legos! I'd probably toss a cushion across the bench seat, but I love the plants organically growing out of the back.
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!
