I remember now why I don't use these pillow cases and quilt cover. My pillows slid all over the place, all night. I knocked everything off my bedside table at one point. The cat decided to sleep by my head (very hygienic, I know,but I don't normally notice her there) and kept sliding into me. The actual Duvet was fine it was just the pillows that seem to have a mind of their own. I am so tempted to buy new ones but I dont need them, so I wont.
