1: Yes re Turkish carpet-weavers
2: No
3: No


Version 2
1: Yes, again Turkey, but this time in relation to shipbuilding.
2: Artisan, no, but I have spoken first-hand with a man who took over a new-built ship from its Turkish builders. He noticed what I did not; that the port and starboard sides are not mirror images, though drawn that way on the plans. The ship is not compromised by the differences, but is imperfect, as I can witness. The explanation given was that perfection was the sole prerogative of Allah.
3: No

Thread-drift warning:

I like the slightly similar [in that it concerns perfection] story of the chieftain building one of the forts on China's great wall. It was suggested to him that he should order extra bricks "just in case" when he had already ordered what he had calculated as the required number. He duly ordered one more brick, which can still be seen lying loose on a ledge half way up the wall of the fort.
