That's an interesting thought - we have 3 sets of sheets and rotate through them. We have cats so we take off one set, put the second set right on and remake the bed so the cats don't get their fur all over the sheets. I suppose we could put the blankets back on to protect it while the sheets were being washed but we just do it this way.
My boyfriend is on the large side but for some reason we don't need to nail down the sheets, I guess we must not toss and turn much ... I like the sheets being loose, actually. Then I have two big fluffy blankets on top of them.
