I'll join in on this one. I am asthmatic, so I prewash EVERY FABRIC that comes into this house. I have also gone through the "bleeding" with fabric, and I have tried every home remedy from Oklahoma to Florida and back again. The problem is that the dyes used in our fabrics are no longer organic, they are chemical dyes. Some of them bleed, but they are no respecter of color -- blues will bleed. I test my fabrics by cutting a 1/2" wide strip about 6 inches long and placing it in a glass of hottest tap water available. If the fabric is going to bleed, that color will show up in the water, or you can lay the wet strip on a solid white paper towel. If the fabric is a bleeder, it will show up on the paper towel. I found a product I use which is a laundry treatment product -- called Ritz Laundry Treatment - Dye Setter. The product was originally intended to set the dyes in hand-dyed fabric. I ordered some online and used it on the "bleeding" fabric -- it stopped the bleeding and/or "set" the dye. After treating it, I re-washed it both with some white fabric and a color catcher. Neither the fabric nor the color catcher showed any of the previous bleeding so I continue to use the product. I make it a policy to test every colored fabric simply because, like Coopah, I don't want to waste time and money making a quilt to have it ruined the first time it's washed by bleeding dyes -- I cannot afford to do that. So I use a product that I know works.
