Do people care about the Quality or merchant robes? I'm thinking about making some (eventually) to trade, but should I focus on getting my silkmoth/worm/thread/etc Q up first, or will it not matter? I realize they give Int/Cha, but it seems most people think these stats are fairly useless.
Also, what affects the Q of silk-related things? Eg do the herb tables, mulberry leaves, water, etc used all affect Q, or just some, or none?
