If I remember correctly, the old time heaviest quilts were not quilted, they were tied. The ones Grandma made seemed to be made with heavy, scratchy fabrics, blanket batting and a soft backing. Probably a flannel sheet.
But it sure was comforting to pull that heavy quilt over me, cuddle down in my flannel gown, snuggled deep into the big pillow and listen to the wind hurling rain at the window in the bedroom.
