I hear it's a reference. Honestly, I rarely prewash my fabric. I have, but I don't make a habit of it. So far I've been lucky. I've not had any problems with running or uneven shrinkage. I wash my quilts in the regular wash with regular detergent and Oxyclean after I'm finished with them. Knock on wood, 'cause now I've probably jeonxed myself.
