I actually threw away a piece of blue batik that never did stop bleeding - not a big piece though - so not a very big loss. I even showed it to my DH - in a pure white dishpan - every time that I pushed it up and down in the water it would ooze out blue die - my DH said it reminded him of an octopus that squirted out blue ink when cornered! I only buy my batiks from quilt shops so it was a nice brand/quality.
