This patch features the Thin Red Line and Thin Blue Line flag below the Twin Towers. The patch measures 4″ tall and 4″ wide. This is an iron on patch with an permanent glue. Turn your iron on high and slowly move it over the patch for 45 seconds and then do the same on the back side of the patch for 30 seconds. Be sure to get the edge of the patch and not just the center. If you have any question on applying the patch there are several helpful videos online.
