When I lived in Ottawa, I belonged to Victoria Quilting Guild, we made quilts for cancer patients, we always did the backing with flannel so they would be warm. It was such a good feeling knowing all your work would be loved and a comfort to those going through it. When my Dad was diagnosed with leukemia, I made him a big block rag quilt made of flannel and he never was without it and told me every day how nice and warm it kept him. He got to use it for 8 months........
