It's so sad when this happens, especially after spending our hard earned money on good fabrics. I was given fabric by a friend, who purchased it at a reputable quilt shop, who also sells fabrics online; the fabric with black background I thought would bleed, didn't, but a much lighter green background fabric did. I kept rinsing and rinsing about 6 times before I got it to stop bleeding, I wish I had remembered some of the color catchers recommended here on the QB. You just never know, and it's unfortunate when it happens. if you've tried several times and it still bleeds, using the fabric as a drop cloth, or to cover machinery or other tools would be my only recommendation, except maybe for dog beds.
