Is there a difference between bleeding into other colors of the quilt, or simply having dye be absorbed into a dye catcher? Not very clear, am I? Here's an example--I have some black premium broadcloth from fabric.com. I keep washing it in hot water (in the washing machine), and every time I do, the dye catcher comes out gray. Now I soaked that fabric in hot water with a yellow cotton that I want to combine it with in a quilt. The water looks a bit gray, but the yellow is fine. Do you think it will be OK to combine them in a quilt?
Next time I will buy the kona black, I understand that it doesn't bleed, but I am thinking I can go ahead and use this one in the quilt--I've got a lot of it.
