plaid is a woven fabric, mostly made of wool, which utilizes different colored yarns that cross over each other in order to create the blocky, linear pattern we all know.

Interestingly enough, plaid is much older than one might guess. There is evidence of Celtic tartans dating as far back as 8th century B.C. British and American manufacturers began appropriating Scottish tartans and creating plaid textiles for their respective markets.

Mixing blue and grey shades, the Blue Plaid is definitively one of our favorite tartans.
