Visible details
Drapes frame an arched passage rather than a window. Long panels establish vertical edges while the room beyond remains visible. Pale walls and a wooden floor make the outline of the opening easy to read, which distinguishes this reference from window curtains.
Room context
Discuss a similar approach between a living area and dining space. Decide whether the panels should remain decorative at the sides or occasionally close across the passage. Views from both rooms help assess how the fabric relates to the arch and nearby wall decoration.
Window questions
Measure the narrowest clear width, the highest point and the fixing surface. Where could open panels gather without restricting passage? Ask how the bottom edge should meet the floor and whether each side needs to move independently.
