That is an interesting idea. Hubby and I have always been opposites. When we were first married I was always cold and he was roasting. Now in later life we have swapped. I made two identical quilts with no borders on the inside edge where they meet in the middle of the bed. We can each adjust the blankets as we like while sleeping but when the bed is made the quilts meet in the middle it looks like one quilt because the patterns match up.
