May you never have to consider using down fill for anything, particularly if you are working out of your home. This shit is worse than glitter, but it makes really fucking cozy pillows and cushion tops. Rich people love it. If you find yourself making deals with the devil to use this shit, then make sure you pick up a down feather bazooka. ( See also my tutorial on how to make your own) They are fun to use, and will make your clean up nightmare less nightmarish, though you will still never be able to completely rid yourself of the feathers. They will haunt you forever. This is a 10/90 mixture, meaning 90% is down feathers and 10% are just regular feathers.
