Hey Carlos,
Very nice
,
I love the curved lines and the mulch / rocks. I also really like the rusty metal edging. I work in the sheet metal industy and have always thought of doing a metal edge and letting it rust. Now, after seeing yours, I think that I'll try a section and see what I think.
I would be interested in knowing what product you will stain the cement with. I have always thought that cement was too sterile looking for my taste. I have a cement drive in the back and walkway in the front that I have considered staining. I'll watch your progress.
Have you considered doing something with the straight lines and sharp corner of the patio?
Steve
