I've just been given 3 matching pairs of very smart single duvets, perfect as we use two singles on our bed instead of a kingsize. Anyway, they don't half rustle! I like my bedding to be silent and soft. As it is, I worry about waking the kids up when I turn around (sleeping in my room). They have had some light use by their previous owner, and I've washed them prior to using them, but this rustling is something else, like sleeping under crepe paper. I haven't used fabric softener as I can't get on with the stuff, and none of my other bedding needs it. They're lovely, a nice, fairly thickly woven cotton, but nothing unusual, just a good quality cloth. Any ideas for softening them?
