Acid-stained Concrete Patio -- Looks like copper! Click the pic for a brief how-to video on doing this technique. I'd love to do this, although I wonder if the acid stain is bad for those plants around the patio.
Turn a large backyard into an outdoor living space by creating zones. THIS is what I mean by "areas" - having different zones for different furniture / purpose - love the look of solid mixed with smaller squares w/ rocks peeking out - not grey ones
