I used Synthropol on this fabric according to the directions from the bottle. It did not touch the bleeding from this fabric. I did not have any Retayne at the time.
Myself and two other quilters who have dyed fabric have seen nothing like this Gee's Bend fabric! It just would not quit!
I would not recommend using this particular fabric in any piece...even a wallhanging. My opinion, take it for what it's worth. This is not my first quilt. ;0)
But I now have a pink blouse that I had to overdye because of splashing while attempting to put a tourniquet on this fabric. Also, the color of the fabric was not at all lessened. It was still a luscious dark red after an hour or so of washing and rinsing. It is a shame because it is wonderfully beautiful fabric.
