It's so annoying that fitted sheets wear out twice as fast as the flat sheets. Yet, it can be difficult to even buy replacement fitted sheets, in some sizes. So, I'm left with lots of pillowcases and flat sheets.
I found a great use for the flat, flannel sheet to my Cal. King bed. In early fall, when the nighttime temperatures weren't cold enough for an extra blanket, but a bit chilly, with just the bedding from summer, I used the flat flannel sheet as a very lightweight blanket, on top of the smooth cotton sheet. Kind of the in-between just a sheet and a sheet plus blanket.
With a cotton quilt on top, it was just the right amount of warmth for me, so much so that I've done the same for our spring shoulder season. I really like that I'm getting more use from a sheet that was seeming useless, just sitting in the linen closet.
