If you live a in a home with exceptional views and architecture and can make the most them, consider using your windows as a ‘wall’ when planning the scheme. The view will lend one feel in the day, but at night when you close the window coverings, these will bring a more solid quality and the material you choose will influence the mood.
This may work well with a wood look metal Venetian blind with a strong and architectural style, or if you have lots of strong light to manage during the day too, a blind like Twist® can be used to control and defuse it with fabric vanes in varying vane widths. If you have full glass retractable doors or windows, consider using modern vertical blinds, as they have a sleek design and stack neatly against the wall when the doors are open, making them unobtrusive.
