T20 leagues have loosened the hold of national loyalty in cricket, but fans in the international game today - perhaps as a reflection of the times we live in - like to display their support on their sleeves (or faces or bodies). One of the ways to show your support for your team is using the country's flag.
In the photo above, from Belfast in 2015, the rainbow seems to perfectly frame the Australian flag and define the arc of the wave.
You can use the flag for more than just waving about. Graham Thorpe employs one as a sarong after being announced as England's captain for an ODI series in Sri Lanka in 2000-01. England lost the series 3-0 and those were the only international matches in which Thorpe led.
It can also double up as a colourful headscarf.
Or a superhero cape.
Or a bikini top when spending a day in the sun, watching cricket.
Or a blanket when spending a day in the cold, watching cricket.
Want to really show your support? Drape the flag over the balconies of your school, like these kids in Ahmedabad do during the 2011 World Cup.
You can also use a flag as a message board.
