<p>I once lived in a ground-floor apartment where the streetlight outside my window turned my bedroom into a stage every single night. The solution wasn't a blackout blind, but a pair of thick, floor-length drapes that transformed the room from a fishbowl into a sanctuary. People often underestimate what curtains and drapes can do for a space. They're not just fabric hanging by the window; they are the room's quiet workhorses, handling light, privacy, insulation, and acoustics all at once.
