I have tried storing duvets in Vacuum sacks but they keep on deflating. The main problem seems to be the plastic sliders which don't seal them properly after being opened and closed a few times. I want to keep my duvets on top of my free standing wardrobes. What kind of boxes, bags would any of you well organised Mumsnetters suggest? I am going into hospital next week for a big op and would love to know that my duvets of all sizes look tidy before I go in. II wouldn't mind boxes because they would stack. Thanks.
