Oh, my. This disagreement has been lingering for almost 40 years.
My friend says that when you make a bed, the top sheet should be pattern-side up. I say it’s the opposite.
You lay it face down so that (1) the occupant is resting in a full-pattern atmosphere and (2) when you lay a blanket on top of the sheet, you can fold it back as far as you want and the pattern is still exposed.
What say you?
