We have a large window with an arched top that needs window treatments because it faces the front our home and people can see our kids messy room or my kids playing as they walk to the front door. We have roman shades on other standard front facing windows. In our master we have curtains, and in the kids bedroom we have wooden blinds plus curtains. All that to say we're open to anything that is functional, but also want something that looks nice. We tend contemporary.
