What sort of idiot designs a paving brick 110 mm x 155 mm? There is no way you can do a simple but interesting pattern or random arrangement of bricks without ending up needing loads of bits of bricks. Two short edges don't equal one long one and the other size bricks you can buy don't help either.
More to the point, what sort of idiot buys that size brick? One thousand two hundred and twenty of them.
On the plus side, our courtyard is getting excitingly close to being finished. Brick-breaking (and swearing) excepted.
