The Lozenge shaped ones (taller than they are wide) are very odd. I much prefer the square stars. It is odd that there are the three shapes, considering how anal us brits are about this sort of thing. Usually we have strict rules that must never be broken. The round and square stars make sense as aesthetic choices since they are of equal size but the lozenge stars are very unusual, I wonder what is behind them. Do stars of other countries have variety of shapes?
