I only have 2 sets of sheets for our bed now & one set got so thin that it started developing tears in it. After a few "fixes" I decided enough was enough with that bottom sheet. Of course we were right smack in the middle of the pandemic & I wasn't out shopping at that time so I got some fabric that I had for a long, long time & did not see using it in a quilt so I made it into a bottom sheet (not fitted). It works like a charm & I just use the "hospital corners" on it. Granted, our mattress is heavy & it's hard to tuck she sheet in but it works for me.
