GREAT idea! We have a king size lightweight down comforter that is beginning to show it's 12 years of wear. It's all white. We both love it, so hate to part with it and they are cost-prohibitive, so need to do something with it, and have always hated how the sides were too short to reach the bed skirt, so this would be a great idea to make it what I always wanted it to be! lol Thanks for posting!
