This bay window has 3 separate openings with relatively wide molding between each, If you have enough depth, the roman shades can be mounted inside each window opening. In this case it looks like the windows were too shallow and the shades had to be mounted above the windows. The wide molding between windows covers the gap between the shades.
I really like this because the color scheme is very basic. This means you can change out the pillows and details EASILY. I love to change my decor, so purchasing colors like this makes sense and I can get a lot of looks by changing the accessories.
