The DAR renewed its lobbying for a state flag in 1922, having gained the approval of the Sons of the American Revolution and other civic organizations. A bill adopting the state flag was introduced in the 1923 legislative session and passed unanimously in the Senate by February, and the House of Representatives on March 5, 1923. The governor's approval was not required and the bill became law, formally adopting the state flag. The law took effect on June 7, 1923, and an unofficial flag was unfurled on Flag Day by the DAR. At the time of its adoption, Washington was one of four states lacking an official state flag. The first official state flag, manufactured by Willis Bloom of the Secretary of State office, was unveiled on July 23, 1924. The new flag was celebrated with a "State Flag Waltz" performed at the Inaugural Ball on January 15, 1925, following the inauguration of Governor Roland H. Hartley.
