Flannel has been cherished for its softness and warmth for centuries. Originating in Wales as early as the 16th century, flannel blankets were primarily made from wool. As time passed, flannel became associated with comfort, leisure, and relaxation. In the 19th century, the cotton flannel fabric gained popularity, offering a lighter alternative. Nowadays, flannel blankets are typically made from a blend of cotton and synthetic fibers, ensuring a cozy yet lightweight experience.
