I got some fabric at the LQS that had a "weakness" in the fold. It was on the sale table. I got it home, washed and dried it. As I was ironing it, it split right down the fold. I took it back and the owner was appalled. She had some left on the bolt, gave it a pull and the whole thing split. Got my money back, she sent it back and they credited her as well. Seems they sent her the "wrong quality" fabric. Ever since, I check the fabric carefully.
