Number four on the list of the Top Ten Design Elements that I love in a house are curtains. After linen, slipcovers, and seagrass – curtains bring so much to a room that they should always be considered when designing a house. Curtains add romance, texture and softness. They can also add jolts of needed color. They bring coziness and warmth to a room or sometimes they add a beachy breeziness.
