Using a chandelier on a covered patio adds an elegant, lived-in look to an outdoor space. Just make sure the patio is protected from gusts of wind, protected by the house or by hanging heavy curtains or a privacy wall.
Open Up : Include a large market umbrella in your patio decor. Besides providing much-needed shade to an unprotected patio, it adds a nice vertical element to the usual horizontal lines of an outdoor room as well as bringing in color overhead.
Lights could also just go from one side of the house to a central thing over the table. Like if I make a chandelier thing, that can be where they are gathered in. We'll see what looks easiest with the house.
