Glen plaid
Glen plaid (short for Glen Urquhart plaid) or Glenurquhart check is a woollen fabric with a woven twill design of small and large checks. It is usually made of black/grey and white, or with more muted colours, particularly with two dark and two light stripes alternate with four dark and four light stripes which creates a crossing pattern of irregular checks. Glen plaid as a woven pattern may be extended to cotton shirting and other non-woollen fabrics.
