The Idaho state flag has a blue background with the Great Seal of Idaho in the center. A red scroll with a gold border is below the seal and contains the words 'State of Idaho' in gold letters. Surrounding the seal is a gold band with the words "Great Seal of the State of Idaho" in black lettering. In the center bottom of the band is a single white star representing the new state. Represented in the seal are equality, liberty and justice and some of the great resources of the state - forests, farmland, rivers and wildlife. The Latin motto, "Esto perpetua" ("Let it be perpetual") appears above an elk's head and behind a shield representing a game law that protects the elk and moose. Cornucopias, Syringa or Mock Orange – the state flower - and the Snake or Shoshone River are also depicted.
Idaho 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.
