Ummm...first of all, let me just say "Eeeeeewwww!!!!!" Second, wouldn't it take just as much time to do that as it would to simply strip the bed and remake it with the clean set of sheets?
Which, therefore leads me to this week's edition of random questions:
If you have a designated guest bed (regardless of it's locale in your home), do you keep it made up for unannounced guests and random drive-by sleepovers, or do you keep it with only the quilt/comforter on it, and make it up with clean sheets and blanket upon the impending arrival of/decision of a sleepover guest?
I, personally, was brought up, that the guest bed looks made up when it is specifically for that purpose. You have your pretty comforter on it, along with all the decorative pillows your husband will not allow you to have in your own room. Then, when you know you're having company to stay in the guest bed, you take out freshly laundered sheets (or at least recently laundered), and make it up, putting clean towels out, as well as a fresh bar of soap, and make sure you're otherwise ready.
I don't think I know anyone who actually keeps sheets on a guest bed, especially when it is a hide-a-bed in a couch somewhere in their house...
But then, I find I'm surprised by something each day.
Tell me about your guest quarters...
