I had that happened to me on a quilt I made my mother. DIdn't notice that the red had bled on the white before throwing it into the dryer so was shocked and upset. Someone on this site said to throw it back into the washer with a color catcher. I did and the bleeding came out............even after it had been dried no less so I was floored and very happy to say the least. I swear by the color catchers these days. I only wash with cold water though.
