Flannel is a brushed, pliable fabric of twill, wool, worsted, cotton or rayon made in tightly woven twill or plain weave and finished with a light napping. Flannel originated in Wales and has a soft, napped surface that partially cancels the weave. Has a dull finish and is made in a variety of weights. It is more loosely woven than worsted flannel with a higher nap and bulkier hand. Flannel shrinks if not pre-shrunk and sags with wear unless underlined. It does not shine or holds a crease.
