Jules51- You mentioned a duvet cover so I am going to ask you my burning question. How on earth are comforters kept in place inside a duvet cover. It would seem to me that unless it is somehow held in the corners it would just ball up inside and add that much more to do when I make the bed each morning. Am I wrong? I have been gifted some beautiful duvet covers and one hand made one and have never used them because I have enough to do making a temperpedic bed without arm wrestling a comforter in a duvet cover. Am I wrong or do they stay in place inside the cover? All of my comforters and duvet covers are cotton. Please help me understand this?
