I have made several quilts using the white Waverly fabric from Walmart. I did not pre wash and they look great after being quilted and then washed. I know the fabric is not as good as the brand names like Kona, but I have made some lovely quilts that have held up well for whom I've given them. I would not use this fabric for a heirloom quilt or a show quilt. And I would not wash it without being hemmed.
