HI thealy --- roman blinds on the smaller side windows and on the larger window with floor length drape side panels hung from decorative rods and finial ends just under the crown molding . Fill the wall to the ends with the drapes for the lux look. The romans can be in a beautiful fabric that has a pattern or stripe and then the drapes can be a plain with texture .

What is your favorite color? I think you can do romans on the small windows and drapery panels on the large one, all in the same fabric. Pick a contemporary medium scale print that features your favorite color. It will work with this neutral backdrop. You may find two patterns in the same colorway that are complimentary. In that case you could use a smaller pattern on the romans and a larger pattern on the drapes. Take a bit of the fabric to some throw pillows for your sofa or use the smaller print for two lumbar pillows in the beige chairs. If you are on a relatively private street or cul-de-sac with no neighbors and little traffic to peep in, you may not need to use romans on the big window.
