Consider the useful role of the treatment

The reference presents curtains, blinds, and shutters as choices that should respond to the room and its windows. Fuller curtains in a thicker fabric can be useful where windows are draughty, while different combinations provide other levels of coverage. Establishing those needs first helps avoid selecting a treatment only for its decorative appearance. Size and fabric matter alongside the chosen shade.

Use finishing details to create continuity

A trim along the side or heading can draw attention upward and give the curtains a more considered finish. The source recommends choosing that detail to coordinate with both the main curtain fabric and the colors already present in the room. Texture is another part of the decision, with velvet offering a different character from a lighter material. Judge color, trim, and surface together so that the window helps connect the overall scheme.
