The original name of the cloth was tweel, Scots for twill, the material being woven in a twilled rather than a plain pattern. A traditional story has a name that comes about almost by chance. Around 1831, a London merchant received a letter about some "tweels". The merchant misinterpreted the handwriting, understanding it to be a trade-name taken from the River Tweed that flows through the Scottish Borders textile area. The goods were subsequently advertised as Tweed, and the name has remained since. Tweed is very strong, rough, and tight-knit, yet flexible and stylish. Used for over a century, especially in suit jackets, waistcoats, and even trousers, tweed is one of the best and top-rated materials for winter wear.
