Try these Quinn drapes by JC Penney. These are very neutral and would look great with both of the windows. Since the windows are close together, the window treatments should be the same. I would extend the curtain rod so that more light comes in your windows, and the drapes act more like an accent to the window, rather than cover them. Good luck!

P.S. - Hang them as close to the ceiling as possible, to add visual height to your room.

You've got color on your TV console. Use that for accents. I would keep the curtains neutral. And yes they should all be the same. Will the curtains ever be closed? If yes then I personally don't like grommet style as they are difficult to slide and eventually will be stained in the spot where you pull them. Hang the rods 2/3 of the way up from the top of the windows and slider. Hang them wide enough that the front edge just covers the window edge and the bulk of the curtain is on the wall. Make sure that the panels are wide enough to cover the window if closed even if you are not going to close them. Take everything except for the TV off the chest, Get end tables for lamps. I think you need more substantial lamps and the end tables need to tall because the arms of you furniture are high. Use the turquoise and green for accents for a coastal feel. Lovely room so far.

May I make a suggestion? Remove the lamps on either side of the TV. It's too crowded and the wires show.

Thank you so much everyone for your help! I was thinking about adding a pretty color blue but I'm afraid if everything else is tan and white that they would look out of place. The walls are white so I was thinking they need some kind of contrast?

IMO that shabby chic cabinet and those lamps do not work in your space As for the window coverings since you really have no color you could go with a nice pale green or blue linen for drapes. Then use that color and one more for pillows accents and you really need some art make it large and you will have the right balance of neutral and color
