I bought a bolt of white muslin at Joann's to cut in squares for a memory quilt for my daughters wedding. I unrolled the bolt, washed it, then started cutting it into 1 yard pieces to be more manageable. I found a stain that went thru the entire bolt in a position that i lost a good foot from each piece. I bundled it all together and took it back. They exchanged it for a different bolt. I opened the bolt there to check it out before leaving. I have also taken fabric back as long as it hasn't been cut and have the receipt. They took it, no problem.
