I want everyone to know that this had a happy ending. I had no receipt, but since you were encouraging me to contact KQ, I did. The person over the phone said they'd exchange it and to bring the fabric in. I managed to say enough about the fabric and where it was located in the store, that it probably sounded legit. (No doubt, mentioning that I had posted to this board didn't hurt, either.)
So over I went. The original fabric wasn't there, of course, since I'd bought all that was left, but they were gracious about it and DH and I managed to find something else that would work. It was a Kaufmann fabric, a bit cheaper, so I made the difference up in thread.
So, they did step up, even though they didn't have to, and I have learned a lesson about inspecting things and keeping receipts.
Thanks again,
Charlotte
