Tweed (a word that comes from the river Tweed in Scotland), is a fabric originally made from rough wool. Warm and resistant, its texture is irregular and elastic. Nowadays it is made from mixed yarns and acrylics.
Normally, it is manufactured in plain or twill weave and often shows the pattern as a fishbone, or herringbone. It is obtained by rotating several strands of different colours together in a thread of two or three layers.
