Who cares if its wright or wrong ?
The flag on ELISEBOYs link cost £275 by a graphics firm in surrey big bucks
and my flag cost £90 and looks the same its not symetrical looks the same but big price difference .
its all down to you when you put it on you move the red stripes where you want them symetrical or not you decide

But i tell you what £275 or £90
or £60 to do it your self well i will tell you which one i would go for i would do it myself
and anyway who as ever seen a mini wavin about in the wind at the top of a flag pole ?
it just looks cool with it on the car
you can have what ever you want on the firm that sells the diy flag will do any design you want
