This topic brought back memories. Some years ago, I was watching a movie and the windows had curtain rods that were on hinges. You could fold the rod back against the wall if you wanted the window uncovered or bring it to cover the window. They had velvet draperies on the rods; but I thought at the time that quilts would be better insulation to keep out the cold. I have never used quilts on my windows but I can see where it would keep out the cold.
