I have used Fat Quarter Shop (they sell everything, not just fat quarters) Hancocks of Paducah, The Virginia Quilter, and eQuilter.com and have been happy with all of them. I emailed Fat Quarter shop once to ask if a fabric background was white or off-white. Not only did they e-mail back that it was off-white, but suggested one with a white background that was exactly what I wanted. Another time I was looking for fabric that had not been released yet and eQuilter.com emailed me back to tell me when it would be available and then emailed me the day before the release so I wouldn't forget to order. Great customer service and great fabric from both.
