i bought some gold batik from a LQS. I thought it felt "funny" so I washed it with a color catcher. The color catcher was a gold as the fabric afterward. Before I use that fabric I would wash it again with another color catcher. Also, my mother always prewashed her fabrics. To Needles3Thread: You may have some uneven shrinkage when you wash your quilt. I would suggest using cotton batting and having it machine quilted with lots of quilting.
