Is it same if I change the "shades" to "curtains"?
"Shades" and "curtains" are slightly different. "Curtains" are long panels of soft material that are drawn from side to side, whereas "shades" are long panels of material that roll up from top to bottom. "Blinds" are another type of window covering similar to "shades," but they have folds or consist of multiple slats of material that can lay flat to block out sunlight. In this case, you cannot change "shades" to "curtains" as they are different items. Ex: Can you roll up the shades? Ex: Can you draw the curtains?
