Sewnoma, I think I might be cold blooded just like your husband. I understand and like HEAVY, very warm blankets....and my husband thinks I'm nuts! Lol! Your idea of 1/2 cool and 1/2 warm is exactly what I did. I took two twin size down comforters and stitched them together. Dh's side is summer weight and my side has the warmest fill I could find. We also have a dual control electric heated mattress pad. He never turns his side on but my side is always on.
