great outdoor project for spring or summer is to build a retaining wall. Retaining walls are used to reduce soil erosion, but they can also be built to create a pretty flower bed. - Flower Beds and Gardens
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!
