I didn't hang it yet, still figuring out where it goes best. Will probably hang it diagonally. I tried to hang one piece using just one hook and it stays nicely. It's light, so one nail per piece should be enough. The paint is brown/reddish with some green in the middle of the leaves. It looks more gold in the picture. It should be easy to spray paint it if you don't like that color. Overall, great product for the price.
