The Delaware state flag has a background of colonial blue, surrounding a diamond of buff color in which is placed the coat of arms of the State of Delaware. Below the diamond are the words, "December 7, 1787," indicating the day on which Delaware was the first state to ratify the Federal Constitution. The coat of arms in the center of the flag depicts a shield of horizontal green, blue, and white stripes containing a sheaf of wheat, an ear of corn, and an ox standing on grass, representing Delaware's agriculture. Above the shield is a sailing ship. A farmer is on the left of the shield and a soldier on the right. The state motto, below the shield, reads "Liberty and Independence".
Delaware flags for outdoor use are constructed of a durable nylon fabric especially developed for flag use. Nylon's tight weave provides maximum beauty and flyability as well as brilliant, fast colors. Its weave helps shed pollution, dirt and grime that the looser weave alternatives absorb. Nylon is water repellent and mildew resistant.
