September 11 is a national day of remembrance for the tragedies that occurred that day, and patriotic coloring sheets like American flag coloring pages can help kids commemorate this date in history. The U.S. flag coloring sheets at Coloring Castle are geared toward younger kids, but older kids and adults can also color them too. They would look nice printed out, colored in and displayed on 9/11 or any other day too, to show your patriotic spirit. Click the link to see the American flag coloring pages.
