I tie most of my quilts and lap robes. I put cotton on one side and flannel. On the other side. Mostly themed fabric that the person I am giving it to favorite thing. I give these away to friends with cancer, children with cancer. Also to newborns and some nursing homes. My grandchildren love them they call them warm and cool. One says summer and winter. They wash and dry wonderful. They last year's and take a hard time. Also add a bag to match for trips to chemo. They are looking in to a plant near by ALlied Chemical which has changed names two times now. For planet putting waste in river and water supy.
