I have been a little disappointed in what I got from Quilted Twins, as far as wide backs go. The weave was pretty uneven, leaving large "bubbles," which were difficult to get even enough to quilt without leaving pleats. The fabric was thinner than many others I've ordered from them. I haven't ordered wide backs from them for few years after that, so maybe things have changed. I'm a pre-washer, so these things may not have shown up for those who don't prewash. I get very little fabric from JoAnn's anymore, but was pleasantly surprised at the quality of a couple of wide backs I bought from them. I do like Hobby Lobby for wide backs.
