Things have to be the right way up. A friend of mine had double glazing in a daisy pattern in her front door, the daisies were upside down. it drove me barmy, she hadn't even noticed.
When I do tiling, the tiles have to be the right way up if there's a pattern - I ripped out a windowledge of tiles in a former life, because then-OH had muddled up the pattern. It's the dressmaker in me.
Other stuff - pah! my house is a tip and I haven't washed up for two days. I'll do it later, there's only me here :-)
