That is a very interesting article. I do not prewash, mostly because I HATE ironing large pieces of fabric. I buy yardage, especially if on sale. I have had major problems with some reds bleeding. I am going to have to try this method on a small quilted piece in a bucket to see if it works with a red I have that I know that runs. I'm thinking table topper with a couple of mug rugs. Thanks for finding and posting the link.
edited to add: I always use Color Catchers, but have had quilts run while being dried. I am now thinking I should be washing the quilts until the color catchers are color free before drying, which I do in a dryer on low heat. Comments please?
