I have 5 sheets, I really only use the bottom sheets (they are all flat so top bottom, no difference) - so that's really 5 change of sheets. They are VERY nice sheets, I'm not giving them away, there was one I thought of giving away but probably not. They can sit quietly in drawer bothering noone. I mean just the sight of them in that drawer (a clear plastic thrifed drawer) is peaceful to me, maybe because it reminds me of one of my favorite activities: sleep . Do I use the flannel sheets in the coldest part of winter? Yes definitely. But that's not that much of the year, the cotton low thread count (ie cooler sheets) are summer.
