Does anyone know if you can get sheets with deep sides to fit feather beds from other places than QVC? I've never been that impressed with NN sheets for the price. I have been managing with one NN sheet for over a year-washing and getting dry the same day but desperately need to get some more,especially as I am going into hospital soon and when I come out will need to be very carefull for a few weeks. I think NN is overpriced but I'm worried about getting deep enough sides to cover the extra depth of the feather bed.
