How do you keep the down in your down comforter well-distributed?

No matter what you do, it will migrate—SO you’ve got to get in the habit of redistributing the down as needed. For me, that meant that about once a week, I took it from the bottom and shook it, then I did the same from each side. I did it when I spread up the bed in the morning. It iwasn’t that big a deal to do—but it would have been MUCH easier if I weren’t short! I also periodically stuck it in the dryer with an anti-static sheet and a clean tennis shoe, on the fluff cycle—maybe twice a year. Since you seem to have down that is specifically running away from you, I recommend flipping the comforter every day. That means what runs away from you one night will then have to run away from you AGAIN the following night, and might help even out distrubution. The comforter I had had 6 (or so) inch channels--but it didn’t have nearly as much loft as your’s does. Our migration issues were more along the top to bottom lines--all the down ended up at our feet.
