Its a friend of ours, I explained I don't do water features, but she insists I just 'try something'. She doesn't want any 'bubbling rocks' or pillars, or over-sized vases with water coming out of them. She doesn't want a pond because she doesn't want to take care of it constantly (unless I explain they take very little maintenance). So, Im thinking, stack some larger rocks in a horseshoe shape, and build the back up a bit, have a little water fall down some 'steps'. Any other ideas for this tight spot? Area is approx 7'x7'.
