Not all of us are blessed to have ANY LQS or even Joann's close by. For me it is WalMart or drive at least a half hour or more for any kind of fabric be it good quality or not.
And I've discovered that most stores have a range of quality and a range of price points. Not all of the lower priced fabric is lesser quality and not all of the higher priced fabric is superior quality.
And besides, some fabric is just pretty...even if it won't pass the 'superiority' test!
