FQs can be 21" as fabric varies in width, but they have to be 18". A half yard doesn't vary. You can return them with a sales slip. I have bought a few of the ones on the wall for the color. They are not good fabric, but they have been true to size and did not shrink. I hate shoddy cutting. My closest JA is in a college town and that's their employment base. I've had some interesting cuts that I've refused, especially with fleece.
