WooHoo ... $2.00 a yard at the LQS! I know that I wouldn't have been happy with just the one piece of fabric and would have had to buy more. You showed great restraint. As to her comment, she knows we quilters buy LOTS of fabric and if the "kidding" tone wasn't in her voice, then it may have sounded sarcastic.
When I present the bolts at the cutting counter and am asked "how much do you need" my response is "I don't need any ... I JUST WANT IT." That is why I'm Fabriholic.
