I am making a red quilt with WHITE contrast. I put some of it in water yesterday, and nothing faded. But I'm not so sure about the rest. I heard you need to use synthrapol. It floats away the excess color, so you need lots of water. It's a soap and sometimes found in the laundry section of Walmart or grocery stores. I had asked at Jo-ann's when I bought the red, and they had no idea what it was or what it was used for. I think you use color catchers with it also. Jo-ann's didn't know what color catchers were either. I found those on line.
