Where did you get the blue fabric? My LQS owner told me if I ever get fabric that has a problem to bring the quilt back. The owner also wants to know so she can contact the fabric company and may not buy more of their fabrics. The shop owner also told me she has only had 1 red fabric bled in her 6 years. I never prewash for 100% cottons from a quilt shop. If I mix fabrics for clothing then I do prewash.
