Do you live in a cold place? I love my flannel sheets, so the bed is not cold when I get in at night.
I bought normal, not flannel, Bloomingdale’s sheets, their own brand, a couple of years ago and they are fantastic. They had a couple of different levels I think, moderately priced. If you don’t have a Bloomies, Macy’s might have the same sheet sif it was a Federated buy. Macy’s might have some less expensive low quality options, so look at the more expensive ones there.
