have never had to treat a large 3 door slider and it is off the dinning room. i’m not sure what way to go because the kitchen and dinning room are some what connected but yet separate and the kitchen only has one update since it has been built and that is a new black and white glass tile back splash, i am going to put very contemporary hardware on the original cabinets and i think that should be just enough of adding new to the old. what type of curtains should i use for this extremely large window . can’t figure out if i should go old or contemporary
