A curious observation.... I have always loved going to anything quilt related because it was an escape from the sameness associated with big box retailers, but I understand how your perception could be formed: after plowing through half a dozen tables of fat quarters, the next six tables lose their appeal because they start looking like the first six and not worth the effort.
Come to think of it, when we lived in Houston, I did stop attending the quilt show every year and went every other year.
