When I first read this, I thought ok if shes in the mood she places the quilt with the warm side up (being warm coloring) and if not on the light side (cooler coloring). Then when DH comes in the room he knows where he stands for the evening. Now come on, I know I am not the only one that thought this, I just spelled it out.
DH and I just flip the covers behind us if too warm or if chilly, pull over us. We quit tucking in the top sheet and blankies at the foot and sides years ago and it makes it much easier to do this when necessary. We don't tug and pull on the covers anymore.
