Use a double treatment for the most flexibility. The flat roman blocks prying neighbors' eyes while still allowing light to filter in. Drapery panels add softness and can block more light when needed.
Bring in the texture! Window treatments are a great opportunity to introduce various textures in the space.
Break the rules with intention. The long drapery panels puddle slightly on the floor in this eclectic Eurpoean-inspired bedroom. It works.
Top down bottom up shades are great if you live on the ground floor.
Keep it simple. White romans are always classic.
Layer sheer drapes with a heavier drapery fabric. Extra softness and function.
Do fill a corner with drapes when two windows meet. The L-shaped rod was a good choice.
