What is a Tartan?
Tartan is defined as a cloth with a twill weave (usually wool) having a unique pattern of multicolored stripes mirrored in both directions that represents a clan (family) or region. Tartans can also be designed as a symbol to commemorate a special event or person.
In old Scotland the tartan was used for clothing and as a banner or flag. Because a family or community worked the cloth together, their clothing was made of the same pattern, and so a person could be recognized by the tartan that he wore.
