Please let me make one note!!  These plaids are not flannel nor are they homespuns used in re-enactment.  They are cotton twills used for the finest mens shirts on the market.  They are 45 inches wide and so soft and wearable.  You will love working with them.
This piece is a large block plaid with red, black royal blue and teal in the plaid.  Remember they are reversible but they are uneven plaids.  Keep this in mind when choosing a pattern.  There is 2 5/8 yards in this piece.
