There is a hidden hero in this picture: flannel. Flannel sheets are essential in a draughty old house. I love our draughty old house, but in winter there is at least a 5 degree temperature difference between the upstairs and the downstairs. Some sort of insulation project should probably be in our future, and we ought to look into seeing if there are ways we can help our heating system do a better job in its efforts to puff warmth into the second floor. Until then, flannel sheets keep sleep cuddly and cosy.
