I used to complain a lot about my duvet cover. It would never stay in place and I had to adjust it every day (or 2 or 3) when I made the bed. I thought it would be great if they just put buttons in the corners so the comforter would stay in place. Well, while shopping yesterday, I found these babies. Yes, I paid $5.99 for them, but I love them already. They keep my comfy, fluffy feather comforter from slipping around. I don't end up being cold in the morning because I only have the duvet cover on me with no comforter in it. Whoever came up with these things is a genius.
